I love your videos and apparently my grandson does too. He’s 6 months old. Every time I watch your podcast videos he calms down and stares at the tv until he eventually falls asleep. You have taken babysitting to a new level. Thank you.

Always such a pleasure, always something to learn. Thank you Ron.

Love your vids Ron, you and Paul Harrell are my go tos for info. Thanks again, man! 👍

Hornady uses temperature stable powders, for extreme temperature variations the outfitters line is designed specifically to work anywhere in any conditions including having sealed bullet and primer so you can drop it in the river without worry.

Hi Ron. Great podcost. Getting back to the twist rate: The powder in any given cartridge only produces so much energy. Some of that energy gets converted into heat, sound, and into the motion of the bullet, that motion being linear - straight down the barrel, and rotational - bullet spin from the rifling. So, by increasing the twist rate, resulting in more spin, what is being sacrificed, linear velocity? Heat? Sound? There's no such thing as free in physics, so by adding more spin with the same amount of powder, there must be someting getting less. Thanks for your great channel, and I look forward to your reply.

Thank you Ron for the always good information on cartridges and their performance as well as just good plain talk about hunting, conservation and the shooting sports in general. It might be cold right now where you are at but Spring is coming. Have a great week.

Hi Ron, interesting listen to the answer of the shooting in extreme cold temperatures, I live in northern Alberta and hunt moose and elk late in the season usually and hunt quite often at temperatures of -30 to -40C. My cartridge of choice is 7mm Remington Magnum I also use 7mm08 and 338 federal. I'm not a long range shooter, I prefer to sneak as close as possible so most shots are within 300yds. Yes the cold does POI but what I do is keep my ammo in my pocket lol, yep keep it warm and load mag primers in 7mm08 and the 338 federal. There's a few other challenges with hunting during cold weather but that's another topic, live the show keep up the great work. Tony.

Great videos and great information. I have had hang fires and miss fires in outside air temperatures at -30F and below with the standard primers, so I went to magnum primers and solved the problem. The top end of the standard primers and low end of the magnum primers are very close, so the probability of over pressures is minimal. Have a great day!!!

Thanks for addressing my comment Ron, you’re the best. Anyway, I didn’t mean that the bones and offal and whatnot shouldn’t be left in the field, you’re absolutely right about that. I only meant that I feel badly about not getting everything out of what I have before then cycling what’s left back to nature. I also always put the bones in the compost.

We always hang the Deer fat in the bushes around the Deer camp, you should see the birds after a few days, Fat and happy! I’ve had Jays and Chickadees land on big game animals while I’m gutting and loudly and excitedly chirp and make a fuss. Its wonderful.

Like your videos Ron keep them coming!

Correct about cold air density vs warm air density. Simple analogy is a baseball hit it the hot July and August nights in Texas , will travel farther than one hit in mid April in the mid 50's in New York.

Another great video Ron, really enjoy your work! Warmest winter that I can remember here in New England, western Massachusetts to be exact. No snow, lots of rain and a lot of lakes haven't even frozen over.

New Ron Spomer video hit play!!

Great content makes me feel like I’m sitting at hunting camp listening to one of my uncles

Boat tail bullets. My only problem with bt bullets was in my TC Contender 7mm TCU with a Nosler 120 boattail. 3 powders and a few charge weights each cured me of using lighter bt bullets in it. It shoots 120 Vmax flat base ok and 130 Sierra SSP great. Tested the chamber attempting to find rifling with the 130 SSPs. The bullet is too short. Apparently this mid/late 1980s TC brand 10” barrel is designed for longer/heavier bullets and has a lot of free bore. The Hornady 139gr also shoots very accurately. Enjoyed this episode, keep up the good work!!!

The 17 Remington, was the first bullet I reloaded in 1966 , I will never forget the excitement and how it made me a reloading fool for life.

Something to think about in cold weather is the impact of cold on barrel steel. Cold causes steel to contract thus generating more resistance which impacts velocity. While heat causes steel to expand. This is why 1st cold shots out of a rifle are slower in velocity than a heated up barrel.

After 3 years of intensive study, I have concluded that the internet opinions cause a significant drop in projectile performance. Anxiety sets in and they just don't have enough lead in their pencil to perform.

There has been a lot of powder company's that have done great at making temperature stable powders

5:05 froghopper was talking about making a demiglace.

If boat tail bullets don't shoot well from a rifle the first thing I would check is the crown of the rifle barrel. Even the slightest imperfection in the crown can cause yaw in a boat tail bullet.

Over a Lab Radar, I get 2800 fps from the 180gr Accubond in my 338-06 and the same from the 200gr Accubond in my 338-06AI. The standard took my biggest whitetail in MO and a nice 6x6 NM bull elk. Both are much lighter and easier to carry than my 338WM, but I still prefer the magnum when travelling to Alaska.

I’ve liked the idea of that 6.5 Sherman short mag

States that allow hunting during the rut will affect the breeding of the does. Studies have shown in those areas the small bucks breed more does than the big old guys. The old guys are hiding more often than not.

I was almost fooled. They pretended they were you Ron. They had me winning a $3000 bow. All I had to do is send them $200 for shipping asking for my credit card number. Caught on to them with the credit card request.

Ron your correct the tallow and fat removed is the proper way to butcher my wife seasons the venison and you would never know the difference between ground beef it’s fantastic most people don’t butcher and clean properly then they say it’s Gamy

The question about temperature reminds me of an exchange in Ice Station Zebra: Capt. Anders: A bullet goes just as fast up here [the Arctic] as it does down there. [Southeast Asia] Jones: ot quite. An insignificant difference, perhaps, but I think you'll find the operational characteristics of the M-16 indicate that a bullet will decelerate as much as forty feet per second per second faster in these climate conditions. It's denser air, you know.

Hello from alberta canada 🇨🇦

Oh man I'm so bummed out I thought I really won. 😭 Just kidding I hate scammers.

I believe the reason the 338-06 is far from .338 win. mag. is that the 338 diameter hasn't gotten big enough to be able to use the faster burning powders that can be used in a 35 caliber. The reason the 35 Whelen can reach such high velocities and energy levels is because it uses powders that aren't used in smaller bore diameters. For that reason the 35 Whelen can come much closer to .338 levels and by using much less powder. The .358 Winchester is another example of this. If the .338-06 is compared to its parent case the 30-06 then the 338 increased the values of its parent by a fair amount.

The other thing that could happen with a 168 grain 7mm if it was a very slow twist rate or if he was using a very long bullet perhaps a monolithic bullet he could just be to long for his rifling. Remember it's the length to diameter that matters. For the .338-06 and other times you increase bore size the rifle is becoming more powerful. The area that the gas can push against is how the energy is transferred and for a given barrel length you will get more power out of the same volume. It will also provide better performance with a shorter barrel since you have the same amount of gas going into a higher volume bore. You actually get one more advantage and this could reflect on your cold weather question as well. As the bore size increases the ratio of bore area to surface will drop. That surface area will be sucking heat out of the gas. That is a parasitic loss. Heat and pressure are basically the same and you can really only get your powder to burn and keep producing gas when the pressure is high enough to sustain your burn speed. After that the pressure and heet will drop as the bullet moves down the bore and creates more room for the gas. Any heat lost into the barrel will drop your pressure at a faster rate. Heat transfer happens faster at higher pressure and different alloys have different rates of heat conduction. I have read that the brass case can actually soak up 40% of the energy of the powder column. This transfer is really complex and even the heat treatment of a metal will affect the speed of this transfer but when all of those surfaces are cold it's going to take some amount of increased energy from the glasses. Cold also slows chemical reactions and this is where modern powders are doing a better job of getting a more consistent range for a stable burn rates. It's my understanding this was a bigger problem in slower burning high energy powders. Single base powders that are nitrocellulose based do well across a large range of temperature. Slower powders are used to develop higher velocity. Because they are slower the bullet can begin to move forward and create more volume and allows you to use more powder without excess pressure. To help develop more speed they also design them to have a higher energy content and di this by adding nitroglycerin. This makes them a double base powder. It's the nitroglycerin that has problems at lower temperature and newer formulas are able to mitigate some of the losses. I have read that some of these are actually triple base powders. These used to only be used in cannon and gun rounds for military use use. For your Canadian hunter if he is really worried there may be advantages to using larger bore cartridges. With the larger bore size they use faster powders already. This is another reason they do better with shorter barrels since there is a trade-off with slower powders where it takes longer to get to peak pressure where you will get faster acceleration making better use if the full barrel length. Since I am going on about internal ballistics I want to say that one thing that you don't hear as being a downside to faster riflings is that it will increase friction and some energy will be wasted although the amount is small. I am really seeing internal ballistics as being somewhat overlooked for most shooters and am trying to understand it better. If anyone knows if any good references that I could get my hands on I really want to study this more and have hopes of doing some gun design. I think some really interesting guns could be developed if we could start using gain twist rifling and sabots. This could make medium bore or even large bore rifles really useful since we could get by with nice short barrels but still have fast enough twist speeds to stabilize popular long range calibers. It even gets better if ultra high pressure cartridges become common.

I make born broth from mule deer and black bear bones. Both are outstanding.

Hi Ron, love your videos and knowledge. I was wondering what you may think/know of regressive reloading. I heard that some shooters are simply popping out and replacing old primers of cleaned cases luring in powder and pressing in new projectiles without reshaping or resizing cartridges to save time and money one reloaded cases.

Talking temperatures- I had once had my 7mm-08 fail to fire even though the primer was struck well. At the time it was a -5F morning. But should I be worried that it may discharge after that? Should I wait a couple of minutes like I did? I left the Buck go that morning to be safe because I didn’t know?

My 338/06 will shoot as flat as a 6.5 credmor 230 grain @ 2740 bc is .617

we have a semi-tame semi-wild mutt cat at our deer lease that always just… appears out of nowhere and meows at us while we gut our deer. Next day he’s always covered in guts and blood from “diving” into the guts and bones hole we have dug and pour everything into after dressing at the gutting station. One of the nicest danged cats I ever met. Tries to rub up on you like they do. But yuck covered in deer guts from gorging on deer bits all night long😂. Hahaha nothing goes to waste!

Faster twist rate barrels absolutely restrict how fast you can launch a bullet of a given weight from a barrel. Nobody talks about it much, but the standard twist rates were always a compromise that would stabilize the heaviest (longest) bullets commonly available in a given caliber, while still allowing good velocity from lighter bullets. Also, sometimes a boat-tail bullet is just long enough to not stabilize well in a given barrel, whereas a flat-base bullet of the same weight often will. I've seen it a couple of times with wildcat cartridges built using a barrel previously chambered in a different cartridge.

Love this video. One of my friends has a 270 Sherman and he really likes it. He tried talking me into doing it with one of my 270s. But to me all the xtra case work isn’t worth it. I’d just shoot a mag round such as my 270 WBY. He really likes playing with 270 cal rifles. He has several 270 WSM rifles and recently barreled one in a 270/ 300 win mag that really woops my loads that where hot for my 270 WBY. What I’d really like to play with next would be a 280 AI. What’s your opinion on the 280 AI or the 270 AI.

Does temperature affect ballistic performance? The answer is yes, it does. Does it have a big effect? Not really. According to the QuickLOAD internal ballistics software (which employs a thermodynamic model for simulating the combustion of the powder inside the barrel) nearly all commercial powders exhibit some temperature sensitivity to burn rate and pressure. Typically, one can expect a variation in muzzle velocity of 1-2 ft/sec per degree F of ambient temperature difference, depending on the specific load. In addition, there are published correlations that show how to correct the published G1 ballistic coefficient for temperature, atmospheric pressure, altitude, and humidity deviations from the "standard conditions" that the published BCs are defined at (see, for example, the external ballistics section in the Sierra Reloading Manual, 3rd Edition, which is the one I have). Of all these factors, humidity is probably the one variable that has the least effect on BC, but it's interesting to play around with these models just to see how small these effects are. In my opinion, the biggest uncertainty in long range shooting (beyond 400 yards or so) is the unknown wind variation downrange, and whether you are shooting uphill or downhill, especially for steep angles. Not every hunter carries with them a laser rangefinder that corrects for shooting angle (although maybe they should). The other big factor in long range shooting is cant. You must hold your rifle as nearly perfectly upright and vertical as you can. Any clockwise rotation of your rifle so that the plane formed by the line of sight and bore axis is not vertical will tend to throw your bullet off target. This is not a big factor inside 100 yards, but it could be a big factor beyond 400 yards. When shooting at a living creature, it's always a good idea to stalk as close as possible to your game to ensure an ethical shot. Just my opinions...

My only problem is with leaving bones out there is if you are in cwd area. Otherwise on public ground it is great debone deer in the field.

Jamie from Australia. I think ron didn’t understand what you meant by twist rate affecting velocity. I don’t know myself if a higher twist rate slows down your bullets. But I’m sure you might be able to find out. Im sure it’s explained in a video somewhere. Now curious myself. I’m going to look too.

Yes very true but you have to remember a buck will have territory about 15 to 20 miles long and it could take him a week to cover it all

Cold air drops chamber/ bore pressure a varied amount as it becomes colder, the pressure drops more. However the cold air itself actually allows for less air resistance and friction on the bullet because it is less dense and USUALLY has far less humidity than warm air does,so the air becomes thinner ever so slightly. So it will not get as much velocity,but what it does get will carry further ,with less drop,however marginal it is or isn't. The longest range hunters ,match shooters and similar , at 1000 yards and beyond ,they will notice the difference. The rest of us, probably won't unless you are in -60 ° f .

I could use some help deciding a caliber for white tail hunting I used a friend's 6.5 creedmoor this past year but I'm trying to decide what caliber I want but I don't want to damage to much meat any recommendations and do you think rib meat is worth it on kansas whitetail

Cold weather does make the air denser and high altitude make it thinner. .I always thought it was the lower velocity in cold weather more than air density. Be interesting to see someone do the calculations for wind resistance, that is beyond my ability to do.

Hi I enjoy your video there is so much good information . I have a question is the 270 win ammunition still available out there here there is no we're to be fond I m just wondering ?

I make bone broth out of deer, bear, elk and anything else. Then I crush the bones and put the bone meal in the garden. It's the circle of life.

Your explanation of the cold air trajectory seems in line. But, having spent all summer in the Tennessee climate working up loads for elk season in Colorado, I have found that elevation and humidity have a bigger impact on bullet trajectory than temperature. Your thoughts?

Ron, rifle bullets are meant to be used in cold air! That's why they wear jackets! Lol

Yup, life is hard on youtube: tons of commercials, with their algorithm apparently still thinking I have a big head of long blonde curly hair and also need tons of makeup; which is ridiculous for an old fart like me ;-) And with every comment I make I win great prizes ofcourse. In the meantime, just about all the channels to which I subscribe suffer from KZfaq meddling with their content through strikes and whatnot. Nevertheless, I still really enjoy your vids sir 👍

I have found that 22lr doesn't group well in temperatures below negative 20 degrees Fahrenheit. I assume that slower powder combustion is the cause.

Dang I gave my social and both of my parents but still waiting for my prize.. Holding my breath

It is more difficult to make a boat tail form with the same precision as a flat base, and that can make BT bullets a wee bit less accurate.

I think anyone objecting to leaving bones and other non useful game parts in the wilderness would be really shocked to see all the salmon bodies in a river.

The smaller buck breeds more doe than the big one do

They, the scammers, are on almost every channel. Almost always have blatant misspellings: clam your prize; massage me for your prize, etc. I mute them and report them.

Suppose years from now your living in space. You have a target set up on the moon. How do you figure your windage? There may be no air , but there are gravitational fields. No bullet drop though. I was just wondering?

White Tail deer fat is not very palatable. Same with it’s marrow. Mule deer is equally sour. That’s why we use pork fat when making our sausage.

Not sure if cold temperature affects the powder/propellant... but cold air is denser than warm air . Still don't think it would make a difference unless it is at extreme distance. 🤔

These scammers are everywhere sadly! QUESTION: Ron, if you were like me and from the midwest and considering deer hunting out west in northern Idaho or Montana where there are very big grizzly's that can kill you, what size of a rifle would you carry that can both kill a deer and as a second choice stop a bear or would you use a pistol, etc? I'm wondering if the .308 or 7mm.08 would work in a pinch? I know Bear hunters typically use huge 45.70's, etc.. 44 mags, etc.. which is fine, but I want to be able to shoot a deer at distance.. ? Thanks for all you do sir! God speed. Tim

Don't think I would want bone broth from CWD deer. I shoot 150 grain nosler interbond long range out of my 7 mag all day and get excellent groups

My deer bones don’t get wasted, my mastiffs just eat them. Those little whitetail bones don’t have a chance against a 200 pound dog, it’s the only way I can afford to give her something to chew on as all the regular large dog toys are destroyed in a few minutes. Watching a $40 toy get shredded makes the wallet sore, even the heavy duty rubber “Kong” brand toys only last a few days.

Cold air is more dense, but moist air is more dense than dry air at the same temperature. Hot air is less dense.

That about cold air and hot air is true I mean if you don't believe it why do they blow hot air in a balloon instead of cold air hence hot air Ballon

What about high altitude?

I got a call the other day told me my extended warranty was about to expire, I told him I wasn't interested he said how about a free rifle from Ron Spoomer? I said sure, so he transferred me to your people, how come, they all sound like they are from India?🤣💦💦💦

Cold Air Kills Bullet Performance? - Season 2: Episode 89 Extreme cold temperature (not air) does not affect "bullet" performance but it does affect "cartridge" or "powder" performance by lowering the pressure of the cartridge. Velocity and energy will be decreased. Conversely hot temperature will raise cartridge pressure. You can say that bullet performance is affected by cartridge performance, but not the bullet itself. Its not the air but the temperature that affects cartridge pressure that in turn affects the bullet. If anything cold "air" is often drier and less dense so "bullet" performance should be better.

your rite, the only thing wasted on a game animal is what the hunter takes out of the ecosystem from wich it came.

Deer/Elk marrow is delicious. Not waxy.

On a average a buck spend. 24 hours with that doe so ,maybe 3 a week

IF YOU GET AN EMAIL FROM ME ABOUT CANNED MEAT, DON'T OPEN IT, IT'S SPAM.

🤠 Ron, I would have to disagree with you on what you told Nick of Minnesota! That 140 grain bullet, out of the 7mm Remington Magnum is moving 3,300 to 3,350 ft/s! In My Experience, With My Big Magnums Operating At Higher Velocities, Flat Base Bullets Stabalize Better and Shoot More Accurately Than Boattail Bullets! FACT, Not Fiction! 🕵️‍♂️

If someone says you won something and you have not actually entered anything then believe me you have NOT won squat. I am amazed as to how many people seem to be falling for these scams wither on the phone, mail or social media.

Cold weather..its not ballistic instability due to hot projectiles and cold air, it's as you said it's air density. Carried to extreme barometric pressure also has an effect. Air density is part of the routine corrections for artillery. Something I haven't heard about in years is over pressure in extreme cold. I know it has happened, but personally, I always considered it an issue with the difference in temperature related expansion/contraction rates between dissimilar materials, leaving a bore to tight for the cartridge.

Who actually fall for the scams???🤣

You should show what it would really look like to give someone a gun. I myself would be willing to receive such a gift from you for the sake of protecting your viewers. You could make a video of it so people could see what it would really look like and that anything different pops up it is a scam. Hint- Voooooooodooooooooo

I thought I won. Texted the number and my phone is blowing up
