The rifle performed better I think than most people realize. Allot different weight bullets and different powders. The big one for me is the different depth to the lands. Really good load development. That was allot of searching I know.

Great video. Really enjoyed and benefited listening. Really contemplated going to 7 mag but love my .280 Ackley Improved. Nice set up also. Thanks

The 7mm Rem Mag is by far the most versatile cartridge. It is one that I recommend to people when they come to me and ask my opinion of the best cartridge. It's easy to load for and factory ammo is usually available. Jeremiah thanks for all your work. Really enjoy the channel.

I love watching these videos since, as I’ve said in your other videos, your presentation style is easy going but to the point. I think the 7MM Rem Mag is in the top three cartridges for North America with the 30-06 and 300 WM/WSM being the others. My hunting buddies and I just had an early morning range session and I was shooting my 7MM Remington Mag, a Savage Weather Warrior that shoots 3/4” groups with 160 partitions at 2965 and 5/8” groups with 160 Accubonds at 3005 which was today’s load of choice. Hopefully a nice mulie buck will find its way into my crosshairs in November.

My 7mm loved the 175 gr partition. ImR 4831. I won’t say how many grains. It’s the old old reloading book. Now days max load isn’t even close. But this put em 1 hole! Really love you showing loads for the 7mm REM Mag!!!

Fantastic video... Fantastic shooting. Fantastic grouping. Thanks

Thanks Jeremiah great over all data and demo!

That rifle is a shooter, great video

Very thorough & informative video-thanks!

Great video, and subbed....I love my 7 rem mag. I recently put a shaw barrel on it, and boy is it fast, and will eat anything I throw in it. RL23 and 180s are a gem...right above 3k fps.

I just discovered your channel via YT suggesting your channel that never surfaced on a reloading search. The ballistics numbers are outstanding for this caliber. I will search your videos for my preferred high performance caliber … .340 Weatherby Magnum. I would have cautious belief the process is the same for the 340; but with different specs from a good reloading book. Very interested in reloading but have never started. Therefore, I enjoy the videos greatly. Very good video presentation.

Nice work, Jeremiah! IMR 7828 was developed specifically for 7 Rem Mag factory loads in the early 60's and, after making its public debut in about 1988, remains one of my favorite powders for the Big 7 to this day.

Enjoyed the video. Thank you.

7mm needs a 26" barrel and 160gr bullets pushed as fast as possible. It also needs a proper cut chamber.

Great video!

I also have a Remington and it loves loads up on the hot side. H1000 powder. Same scope. 150 to 162 grain bullets. I also found the same as you. 665 yards in Montana winter. 150 grain federal fusion bullet. 5 out of 5 shots on a metal plate 14" high by 8" wide. Got a group of 5 shots less than a 4" spread. I couldn't believe it. 162 grain bt hornadys also did amazing with just over a 4" spread on 5 shots. 665 yards. No muzzle break but I didn't have an issue with recoil until we got up to the heavier bullets but my rifle doesn't like them.

Very good and informative video. A similar video on a 25-06 would be awesome to see.

Factory barrels generally move quite a bit after they warm up. Usually after 3 shots you start to get wandering from barrel curve. That gun with a match barrel would be absolutely amazing. Keep in mind that it would be totally unnecessary for hunting, but a great comp gun.

very good info! well done..

I've got a Remington BDL in 7mm Remington Magnum that was made in May of 75 with fluer de lis checkered stock. I use the 139 gr. Hornady Interlock bullets for deer and 175 nosler partition bullets for elk and bear. I've never had to chase nothing whatsoever because it untracked them! I am a handloader myself and I ain't giving you what the rest of my recipes are because every single rifle is different, albeit it is microscopic.

Increíble video, dudo si comprarme un 7 mm y me acaba de enamorar ....que precisión , da la sensación de poco retroceso aunque todo el mundo dice lo contrario....maravilloso vídeo, tirador y arma. Enhorabuena

The wording of the title caught my eye.....the rifle is built "ON" the 700 action. Can't believe how many times I see in print a rifle built "off" of a 700 or other action. Or, based "off" of a particular action. I have yet see a rifle built off of the action, usually the parts are installed "on" the action, not "off". You got it right. Oh, and the old 7 Rem Mag is a good round. It's the Rodney Dangerfield of rifle cartridges.....it never gets any respect.

I'm using a similar setup with a 24-in barrel 1 and 9 twist Remington but I went with hodgdon 7977 powder with 150 grain acupbond LR getting a .6-in group or better just under 3100 ft per second. Very clean powder too. I didn't bump the charge weight up to Max since I was getting that good of group. I didn't figure 70 ft per second. Was going to matter that much, especially for a hunting rifle

I moved to Wyoming, some 38 years ago , I was there 9 years. I arrived there with an old tired 30-06. Every other Hunter I encountered had a 7mm mag and they ALL hated the 30-06. I got really tired of it. So when I got the money together for a new rifle, I purchased a 300 win mag. That pretty much shut the 7 mag fanboys up.

I'm in the process now of working up a load for my bergera hmr wilderness in 7mm mag ,hoping on the new load of 175gr eldx with h1000 will give e me what I'm looking for ,high bc bullet with a hotter load hopefully will stabilize from my 1, 9.5 twist barrel. ,, very good video ,subbed to your channel.

Outstanding. Very happy with my 7mm RemMags. Retumbo, H1000, IMR4831, IMR4350 & IMR4451 have given excellent accuracy. Thank you.

Jeremiah you have scored another home run with this video, no doubt it. The 7RM is so much for to handload for , me being a target shooter the 160/162 Gr BTSP’s or the 168 Gr HPBT from Sierra are more to my liking. For powders I stick with the original powder IMR-7828. That break on your rifle really controlled muzzle climb and recoil, can you give me more information on it please ?

Great video just bought a Remington 700 in 7mm Remington magnum can’t wait to hand load it .sorry if I missed it but what is the yardage you are shooting at thanks

Great job Jeremiah ! Here ( France) it's not easy to findAmerican powders , we use finland ( Vihtavuori) powder , swedish ( Norma) powder ans swiss ( RS ) powder ans French powder ! I shoot the 7 Remington magnum ! He's great calibre ! I have a 7 weatherby magnum and I love too this ammo ! When you show us a vidéo on the 7 weatherby magnum ? Thank you so much !

160gr Nosler Partiton and a good snort of IMR 7828. The ultimate 7mm load for anything in North America.

Thanks for the great video. Was impressed with the 162 gr Hornady group. What jumps to the lands for that bullet?

I envy your groups with the Trophy Bonded bullet. My attempts with the original bear claw bullet never did provide that level of precision. However, I find Jack Carter's design to be so appealing that I will gladly take 1.5"groups and let the bullet do the rest. My personal shooting restrictions keep my shots inside 400 yards so I find that level of accuracy acceptable. These trade offs make for good campfire banter, I think.

A really great video. 20 years ago I reloaded with a Lee loader press. I haven’t reloaded since but I want to. I inherited a rcbs auto, but I don’t feel comfortable with it. Your video was over my head and skills, but that is where I would like to be. I do have a 7mm that I have only shot factory loads and it hasn’t grouped well yet. I hope to find a load that this gun will like. I have been able to pick up powders and some primers. I think I have some nosler and some Barnes bullets. But not sure where to start. I think my first task would to just load a box of shells to get comfortable with my dies and the press. Any suggestions?

I get my load data at 300 yards. It seams to tell a lot.Thanks for sharing.

I use a 215 Fed primer in most of my rifle load's.

168g Berger VLD hunter 0.008 in the lands with 69.8g Retumbo. The target bullet at 168 just shot 3/16 at 1000y (two shot group). Boo Yeah, awesome video

rem 700 true flight barrel NZ Barnes 150 hollow point 64grn H4831SC 3 shot group 100mtrs one keyhole Hornady cases Winchester mag primers. Never had any gun shot like this one.

Great Video!! The only nock is that I think a belted magnum deserves at least a 26" barrel. I'm not worried about the extra lil' bit of weight. Performance is a bit more important to me. 30-06 or .308 is better suited for a 24" barrel. If you're worried about getting stuck on a branch with a little longer barrel, your not slung right, and if you're hunting game in thick brush, use a 20" 308. Too close to worry about velocity at such a short distance with the right bullet construction

Late to the party but first time KZfaq referenced your channel. I'm busted up pretty bad and full of shrapnel. My body doesn't care for heavy recoil but I'm looking at 7mm Remington Magnum, 7 prc, 6.5 prc and the dark horse 6.8 Western, (components and factory ammo especially in my area for the 6.8). I have owned lot's of different cartridges with the exception of those listed. I handload for .223, .243 Winchester, 6.5 needmore and .308 Win. My thinking is maybe a trip for elk or bear sometime. I shoot the 6.5 creed and 308 to 1000 yards pretty regular and 1500 less often. If I were to make that trip I would like a little more getty-up and distance than the .308 Win. Out of those I mentioned, recoil, availability of reloading components and factory ammo in the decision, the 6.5 prc and 7mm Rem Mag with a good break or can seems to be best choice. From a factory rifle which would be your choice? Here in the Bluegrass state the .243 is very versatile as is the 308 and 6.5 creed. So this would be a lighter weight setup most likely.

I really like how you built that rifle and your results. Great video

Enjoyed the Vid! Where can we find info regarding your portable Shooting Bench?

i have done a 3 shot group at 100 m. with ELD- X 162 GN. 6 MM Sako Finlight 7mm Rem Mag

I use a 154 SST bullet with RL17 for my deer hunting load. I will probably use a nosler or barnes a little heavier for an elk load. I have an old Browning Gold Medallion A-bolt that shoots very well. The chamber is really tight as when my friends are shooting none of their fired brass cases will fit in my chamber. I have had the action cerakoted and will probably have it placed in an upgraded stock at some point soon. Just not sure what stock I want just yet. It would be nice to have an adjustable cheek rest tho.

Great job sir! I thought about getting the 7mm Remington Magnum for my last rifle purchase but not many are made with a barrel twist fast enough to shoot the heavy bullets. I chose the 28 Nosler and loving it. With 79.6gr of N570, the Berger 195 EOL I’m getting 3003 FPS, ES 16 FPS out of the Bergara Ridgeback with a 26” barrel 1 in 9 twist. During load development had to shoot 3 round groups because of lack of LG rifle primers. Shot only one 5 round group after choosing the powder charge and got a 0.402” group. This week is one more test with 24N41, shot 3 rounds, 85.2gr of 24N41 during the N570 testing and had great velocity but a higher ES. Both the 190gr A-Tip and the 197gr SMK also shot excellent out of the Bergara but Berger is made here in Arizona. What part of Arizona are you? I’m in Cochise county, Huachuca City area.

I will start with the fact that a magnum shows very little deviation in group size at 100m. You must do group at 200m to accurately show group sizes. Depending on the temperature at the time of shooting, generally you cannot shoot more than two or three rounds without letting the barrel cool. Evan New Zealand

What do you mean by "vortex rings, also made by seekings"?

Very light charges? Nothing near Max? Some nice shooting, but surprised at the OAL variances and choices made.

Try 150 grain ballistic tip Nosler with 63 grains of that 4350. if and when you can get your hands on any.

That muzzle break is awesome. Can you send me a link wear to get one???

Need tips on reloading belted magnums... including this new fangled die that assists in case reloading life...

I have a couple questions, why not use a bore chiller between shots to try and get best accuracy, since in hunting most shots are cold bore, also are you going to take each load and play with powder and jump to dial it in? I have been reloading since late 80s and personally love 7mm

Do you shoot 7mm o8 have you got one for load data for it?

Any plans for a video on 7mm-300 win mag or 7mm practical

Would coal length in any of these loads be safe in most factory rifles, thank you great video

Where are you getting the powder, I sure can't find any a the suppliers luckily I do have some of these powders but no Retumbo or H-1000 or Reloader 22 I loaded some with IMR 4350 and H4831SC and IMR 7828 I was lucky to get some 215M primers the brass I have says Weatherby but they are Norma

Are a lot of you guys finding out that the reloading data for 7mm rem mag is very conservative? I’m a good bit above max for all my loads in my rifle. My other rifles in other calibers usually show me pressure signs pretty close to max.

I can't beat those 175 elite hunters.

Why change bullets with every load?

Just stuffed some 175 Hornadys with IMR4350 for elk in my M77 7mag. They're doing well. Nice video

2 questions…. How much does it weight? And why did you use up 1/4 - 1/3 of the barrel life just putting holes in paper? That looked a whole lot like a benchrest approach for a hunting rifle. You did a fine job just seemed too tedious. I get it, accuracy/ precision check check..

Another excellent video! I'm a 7mm fan, but I'm not a belted magnum cartridge fan. I'd like to see videos on the 7mm-08 Remington and/or 280 Ackley (AI) Improved cartridges which are my 2 favorite 7mm cartridges. I use Federal 215M primers and IMR-7828 in my 280 AI and Hornady 154 grain Interlock bullets with excellent accuracy. My rifle is a bone stock Savage 110 Hunter with a 22 inch barrel, DNZ Hunt Master low base/rings and Leupold VX-II 3-9x40mm scope.

Surprised you don't allow the barrel to cool during a string. 7mag generates a lot of heat in a barrel quickly. Could contribute to your results

I have a reminton 700 long range Shoots one hole groups at any range With my hand loads just neck sized cases

It's kinda funny that 7mm rem mag with a 24 inch barrel is very close to a PRC with a 30 inch barrel in your other video. I thought the PRC didn't need a long barrel to perform Just goes to show the 7 PRC is all hype.

What is the make of that rifle as i am in the market for a 7mm rem mag

Where can I get that press stand? It looks like its bolted down to the table. I would like to get one.

My 7rm won’t group bullets above 150gr (factory loads). If I want to shoot a heavier bullet would reloading my own be necessary or does the gun just not like heavy bullets?

Anecdote, vs Antidote.

i see you are doing as well and there is a little wind

fire form 7 weatherby brass in the 7 rem mag pick up 4 grains case capacity 180 bergers 3150 fps and 162 eld m 3300 fps out of a browning xbolt with retumbo on both lab radar and magneto speed chrono

I cant decide on 7mm rem mag or 280 ai. Atm rebarreling my tikka t3x lite 300 win mag with 150 free bore 1 in 9 twist 25 inch barrel heavy barrel will be my 500 and in elk gun using 200 grain barnes lrx using ai mags

Do you think a howa 1500 with a 1-9.5 twist will stabilize factory loaded 175gr soft points? I don't handload unfortunately, and want to run heavy bullets.

Anecdote my guy

Did I hear him say the COL was 2.850?My new book says 3.290

Try tuning you ammo with the EC TUNER muzzle brake by ERIC CORTINA. ...you won't be disappointed. ..

I wonder how hornady 139 grain does

The secret service snipers use 7RM in 40XB rifles. I'd like to know what their ammo is.

Question, was this a “brand “ new rifle. In your comments you stated that factory ammo had been shot through the rifle. I assume you did some sort of either cleaning and/or barrel break in throughout the day or two of testing? Also, what is your standard cleaning process over a 100 or 200 shot development? I would comment that to get your headspace in the beginning you achieved that measurement by using a fired case, presumably from Factory ammo? Was it Norma ammo? You just kind of jumped to the measurement, but didn’t necessarily explain how you got that. Again, there are new handloaders that would benefit from the small details. I currently have a subscription to handloads online, and have used it to begin my load development and want to thank you, as the info has helped me get straight to the bullet / powder combo I am looking to use, as not all books have enough data to overlap for particular bullet/powder combos, so thank you.

The spreads say you need to add more powder. Did you even measure the case heads with a 1" micrometer to check for pressure? You are a reloader more so than a handloader.

What barrel length on you test rifle?

Letting your brass roll off the table into the rocks isn't the best for reloading those later. It would have been interesting to have another shooter do the same loads and see the overall performance. Every rifle has a specific recipe for bullet reloading and there is a lot more than powder and measurement of such. When one switches bullets, this opens up a whole load of specifics that has to be accomodated. Max charge doesn't mean most accurate.

NEXT TIME --> please show the reloading die over your bench. Not blocked by the press. Thank you

280 बोर राईफल के काटरेज मिल जाते हैं आप बना सकते हो कर दो तियार हमे ले लेगे

How should I start off with this comment? Ok, to begin, you have to read my long diatirbe if you want to categorize it as such.I am now at the ripe old age of 81,(age 15 was my first introduction to a mans' world of hunting. Killed my first deer in NEPA with a 30 WCF..1 shot kill) still shooting, rifle, pistol competition. I manage to hold my own. That said, the video has it's high points and has some impressive results. Oh, I own, and shoot a 454 Casull. So I am not adverse to brute force and horsepower. Nuf of the personality stuff. Not to disparage the video or the fellow doing the video...far be it for me to do that. to get to my point. My first introduction to "big game" was in 1980. A friend invited me to a hunt in Montana, an elk hunt. I jumped at the opportunity. What shall I bring, I said? I listed what I had to shoot to him...all ok ,but do you have or can you get a 7MM? I answered no, but should I get one? He replied, if you can borrow one, or afford to buy one, get one, cause that's the caliber of choice. I went to our local dept store. (at that time, you could walk into a Walmart;Two-guys;GovMutual) store) Not being a "big time" hunter", I had a choice of buying a .270 or a 7MM for the same price at the whopping figure of $150 each! I should have bought them both! But, I chose the 7MM due to monetary restraints. I purchased the Ruger 77 in 7MM. To make a very long short shorter than you care to read, I used to...still do, participated in long-range competition to a lesser degree. Getting to my point. I equipped my 7 with a Redfield BDL accu-tac scope 3x9. I handloaded and shot the 7MM out TO 500 METERS. Getting the results I felt comfortable with, I flew up to Montana. Cutting to the chase, we hiked for several days whiteout success. On my last othe next day, e spotted a "brushhead"..Montana verbiage for a small bull. Having no other choice come back to SoCal empty-handed, I shot....missed! He said, my friend, said he's about 450 yds. I adjusted my scope.( missed calculated the yardage...18 in vs 30 in in the scope). I raised the elevation to max which was 650 yds. As the bull was walking uphill, I kept raising above and aimed above the antlers. "One shot kill below the shoulder bones"!!! The moral of the story? Luck, perhaps. Bullet placement. Perhaps. Ability. Perhaps. In the final analysis, I did it. My first elk hunt and killed my first big-game animal. I'll tell you this. Hiking the mountains of Montana is no easy chore. You all ask, ok, ok, wondering what load you were using? To answer that with some sort of timeline. I was an armature reloader. I stated off making cast lead bullets. circa 1970. I progressed to rifle. I did not know anything about ballistics...bullet drop; VDL. I just shot to enjoy shooting n hunting. I was told....Sierra Bullets are what you want to shoot. Ok, I know I am getting long- in -the tooth so to speak, Here it is my load: Sierra seconds, not a misprint. Sierra 2nds: 160 gr SP. 68.0 grains IMR 4350, CCIM primer. The 7MM cam kill at most distance with any kind of bullet if hit in the vital area. What else can I say? I have the friend to verify my statements. ENOUGH ALREADY1 I've already expressed my thoughts and feelings on another 7MM post.

280 बोर राईफल का काटरेज भी 7 mmका होता है

Yes les bowman invented the cartridge not Remington 7mm magnum . Remington was scared to buy them rights . Because fear of the death of the 280 ... we can all see what happened..

Man, I didn't understand any of that stuff about the dies in the beginning. I guess you can't just buy a set of 7mm dies and go to work.

Why does every one use junkie digital calipers ? Get you a Starrett dial calipers

Handloading is something from the past. Primers, bullets, cases and powders, they don't exist anymore! (Or Americans hoard tons and tons of those?????)

I think your barrel is defective seriously! Send it to me and I'll give it a once over and get it to where it needs to be. 😂

Every remi I have had shot like shit,

Terrible camera placement

Ya lost me at Remington 700. Bye

For deer try 66.5 grs of IMR 4350 BEHIND a swift 150 gr scirrocco. 3200 fps. For Elk try a 175 gr nosler partition behind 62.5 grs of IMR 4350 .2975 FPS. REM 9.1/2 M PRIMER USED BOTH LOADS. SHOOT MOA IN MY 700 BDL .Have never failed to put game down QUICK AND FOR GOOS. 1 SHOT KILLS.
