Very thorough, as always. Really appreciate these vids John! Keep em coming

This guy is hilarious they have been making the lapua for probably 30 more years than the other 2 now which do you think they have more of🤬🤪🤣🤪🤣

I promise you there's more old military ammo laying around than these 300 mags and other crazy shit!!! Keep playing around the way our country is going and you are going to have clubs not guns!!!!

When they come out with something that can compete with the 338 lapua I might consider it but its been out a lot longer and everything is more available for shit hits the fan y'all keep going with these rare calibers and while y'all are swinging your guns like clubs me and my 308 and 338 lapua will still be busting targets!!! These special rounds are great until you can't get them!!! Stay with old military callers and you can always get ammo!!!!

Still going to say la pua❤

I think it's hilarious that people actually think that there is something that can compete with the 338 lapua unless you get into niche rounds! The 338 lapua can hold more powder and more bullet weight so you explain to me with basic math how you can do what the 338 lapua does!!! Shit a 50 BMG can't do what a 338 lapua does!!! Just because you can't afford to shoot it doesn't mean that its not a far superior round for long distance! Yeah you might get 1000 yards try to get a 2 mile shot on steel!!! Exactly you can't that's where the lapua comes in!!! Period the most accurate commercially available rounds!!!

Twist rates stabilize heavier bullets.

based on interviews with Hornady spokesman on Ron Spomer re 7 PRC they have been forced to adjust recipe due to powder not available. will always be errors between claimed ammo and what reloaders and shooters find so many variables.

They lie about b.c and having temp stable powder. I quit calling it lying and now call it "marketing".

Vary good video! Really enjoyed it! Makes me want to and get out some factory stuff.

Right now, I don't trust Hornady's numbers.

Good video. I am beginning think that the quality of the barrel is the really is a big factor in velocity, the interior finish and such. I did the same type of test last year with my rifles in .308, .223, 7.62x39, and .270. I was mostly concerned about the .308, as it's my hunting rifle. It's a custom 700 with a 22" barrel. I tested 25 different factory loads, and all but one were at the box velocity or better for an average, and the one that wasn't was Barnes Vor-Tex 168gr and it was 50 fps slow. All of those same loads were a minimum of 150 fps slower in a 20" Browning BLR from the late 70's, some were 200 fps slower. The ten 7.62x39 loads that I ran through a Howa 1500 Mini with a 22" barrel were also spot on the box velocity for an average. I only had one .270 load, Hornady 140gr American Whitetail, through an old Mossberg Maverick 22" barrel, it was 250 fps slower than the box velocity. Interesting enough, the .223 loads (15 different loads) weren't consistent across the board in a couple of 22" barrel T/C Dimensions. This I found a bit perplexing, as those T/C 5R barrels were very smooth and those rifles still shot MOA or better with every load. Some were spot on the box, some were much slower, and Winchester 5.56 white box was 300 fps faster in the T/C (gasp I shot 5.56 in a .223), and 400 fps faster in a 16" AR in 5.56. There was little to no difference between the 16" and 22" barrels, most loads were within 50 fps in the two rifles, even given the 6" difference in length. The two most consistent loads in both rifles, velocity wise, were ADI 55gr Blitzking and ADI 69gr Matchking,

Wish you had included the 300 PRC.

I wouldn't call changing your packaging with every new powder supply "lying." The information is always just general information and your barrel will always be different than their test barrel anyways but it is intended to generally convey the load parameters within reason. That said, should you care more about how the load performs in terms of velocity and disregard consistency when it changes? I know at least one manufacturer loads for stability and accuracy, with velocity not at the top of the list. Perhaps they should have to list SD/ES numbers too? Proven group dispersion? It's all just controlling variables to deliver a great product that will perform different in your barrel than anybody else's.

Eventually someone that's does the tests correct!!! Thanks as always great vids!!!

26 inch is usually standard .

Look at all those short projectiles from the 50's at around 5:00. No one was thinking about BC or twist rates back then

Some factor ammo uses faster burning powder and you can obtain the same speed even from short barrels.

Dadgum ….that video cost some scratch lol

Why tell the truth? Nobody will buy it then?

I HHAVE BEEN SHOOTING RIFLES FOR 45 YEARS. YOU YOUNG IGNORANT WHINNERS B*TCHING ABOUT THE HORNADY 7MM PRC VELOCITIES ARE SILLY IF YOU THINK THAT IS UNIQUE TI HORNADY OR THE 7MM PRC.

Doing your own testing is the only way to go. If the ammo from a similar length barrel is in ballpark on average, +- 10%, I would not "dis" the mfg. for their numbers, because different guns different temps and elevations, etc. However, if I were getting wide extreme spreads from the ammo during a session, I might have more of a problem with some of their claims. I am not going into long distance precision shooting with factory ammo anyway. I have been fairly pleased with most hunting ammunition and almost all my shots will be UNDER 200 yards.

Back in the early 70's one of the Gun Digests had a great article "Bull with the Figures". The early Speer reloading manuals also used to have tables of the velocities they got using their rifles and factory ammunition. If you have access to one of these manuals from around 1962 , check out the factory velocities they got with the 7mm Rem mag and factory ammunition.

Nonsence Not all barels are created equal same with rifles and ammo if a load produces velocities with an ES of 80 ft/ sec you are good

I think we are seeing the same issue with chronographs that has been seen with bore scopes. People thinking that things are an issue that really aren't. People were taking game just fine before everyone had a chrono in their back pocket. Nothing has changed folks.

Hornady is most definitely misreporting the velocitiy for their 7PRC Precision hunter 175 eldx and has come out publicly admitting as such. (See Ron Spomer's podcast interview with Hornady). They say this is due to the powder shortage and they have had to switch powders. The box still says 3000 ft/sec but most people are getting closer to 2800. The 7PRC is a long range precision rifle and 200fps makes a big difference at 500 and beyond. The 7PRC is basically a 7 rem mag at those velocities even with the high BC 175 eldx compared to a 162 eldx out of the 7 mag. While we can understand and give them a break for having to deal with the powder shortage, what is not OK is them not adjusting the advertised velocities on the box hoping we wouldn't notice.

As always, good stuff.

Reading your title I can tell you probably went to school in East Texas too 😂 I went to Palestine

Good video and good advice. Your mileage may vary 👍

I saw something similar to this on Reloading Weatherby. I'm glad to see multiple KZfaqr content creators calling this out.

Very good video, John. Anyone contemplating shooting game at longer ranges should shoot the ammo they plan to use through a chronograph beforehand so they can know the actual trajectory they are getting to make an ethical shot. You can’t simply look at the chart on the box of ammo and go by that - at least not for longer ranges.

Very helpful. Many thanks. Well done.

Hornady should advertise a list of lot numbers that have been mucked with.

You are the most thorough guy on you tube not hating on calibers just stating facts. Breath of fresh air thanks!

My Weatherby ammo is expensive but it gets the velocity it says.

Great video! Thank you!

This is a huge problem with .22lr. They say it's high velocity, but what they don't say is that it is only HV out of a rifle.

Ammo companies should be required to put test barrel lengths on the box. Shouldn't be a problem if they aren't trying to be dishonest in their reported velocities.

The definition of accuracy:....the quality, condition, or fact of being exact and accurate. Come on Hornady

Some of the 7mm magnums and 300 Winchester magnums have 26 inch barrels

I have a question. If you sign in a rifle at 85° during the summertime then do nothing else and go hunting and the temperature is 40°. What will the results be? will it have the same point of impact will the groups differ?

Yes and no in my opinion no because I'm sure major ones like buffalo bore, underwood, hornady, federal, and many others do chrono their own rounds but at the same time yes they lie because they sometimes use unrealistic barrel lengths like 20 inches for 5.56 while most people use 16 inch barrels or as an example hornady superformance 223 advertising 2900 with a 75 gr bullet but from a 24 inch barrel while most people are probably running 16 inch barrels or 308 ammo speeds coming from 24 inch barrels while alot of folks like 20-22 inch barrels since they are more handy

The time Rigby spent in America had to be educational.

There is nothing wrong with what Hornady is doing. As directly stated in their response, consistency is paramount to speed as it pertains to accuracy or "precision". If you are buying factory ammo, despite being better than it has ever been, you are choosing the 'one size fits all' and getting exactly that. Custom tailoring incurrs additional cost. As in; testing and publishing velocity for every lot produced will increase the sale price. No precision marksman who reloads would mix lots and expect consistency, on any component. If you take the shortcut, you except the outcome.

Does the outfitters 160 grain cx bullet works pretty good for the 7mm prc ?

Very informative video and discussion! Thanks!!!!

Seems like the 375 Dakota is pretty much nonexistent

Why I load.. I know exactly what I'm shooting. Great vid!

Excellent knowledge is power listen and learn.. ✨👍😉

I have and love all 3
