That guy is a bumbling idiot and if memory serves me he was shooting it out of a Ruger American. You can hardly expect one of those sewer pipes to get top velocity. Plenty of people are getting as advertised velocity with good barrels and chambers. My 22" Seekins is getting 2935 out of the gate with 175gr ELD-X and that was the first 20 rounds through the gun, the barrel will speed up some too as they always do.

I can tell you this. I rebarrelled my RM to a 7.5 twist. I'm shooting 195 Bergers at 2950 and they are making bughole groups. (It is a 29" tube)
I just think it matters if you want to buy a new gun, rebarrel an old gun, or if you are ok with shooting 168 gr boolits. The RM has the same muscle as the PRC when they have the same twist. If you simply want more uumph, look at a 28 Nosler, 7 RUM or like someone else said a STW. There are other options like a 7-300 WM, 7-300 Norma, and numerous other wildcats to push faster.
I wanted something that would send the heavies at 2900 fps+, and didn't want to buy new brass and dies. The RM was the ticket for me.
Hope this is helpful.

I've had two 7RM barrels from him in '12 and '16, both ran 180hybrids about 3030-3040
He certainly does something a little different with his chambering.

I'll let you know what I think in a couple weeks. Had a 300 RUM in a Rock River barrel that was shot out. Action was blueprinted so decided to go a different direction and am having a Bartlein 7 PRC 1-8 spun on it.
Since I reload it looked like a fun round to play with

I have a metric ton of brass for 7mag so if I make the switch to tinker , someone will be getting a deal on it

Funny, watched another video today someone chronographing 7PRC factory Hornady Match ammo, box says 3000fps for 175's…guess what? Does only mid 2800fps. The more videos showing this proves the HYPE surrounding these PRC cartridges…
It isn't the guns they are being shot in either…
It is quite obvious that their velocities are rather inflated to try and match the 6.8 Western…
Cheers.

Hill County Rifles shows velocities out of 3 different barrel lengths in their Rifles with factory ammo.

when you strike upon the rifle/ cartridge combo that works for you, makes little sense to change. That said , for a lot of us this is a hobby. Experimenting is the fun of it all.

Yep, not as advertised. Barrel is a 24" Proof CF. Pic of velocity was through a new barrel. It sped up to 2889 after 100 rounds, but it's still slow. Accuracy was 3/4" @ 100. I can load for it and will be doing so soon. I'd be ****ed if I couldn't load. Marketing burnt a lot of people I bet. I'll be pushing Berger 175s. I have R26, H1000, IMR7828 to try.

Reached 3150 fps with the 7prc and n570 out of a 26" barrel with ADG brass. Factory ammo these days is garbage, so is the hornady 7prc brass.

It comes down to what is defined as "Better".
The 7PRC was designed to take advantage of the heavier high BC bullets that were not available in 1962. Most factory 7RM rifles are too slow of twist to take advantage of those bullets. It's simply the evolution of bullet development that demanded a new caliber with new faster twist factory rifles. If you hand load a 7RM throw on a fast twist barrel, buy some heavy bullets and be happy.
Side note, I've never seen any factory advertised velocity live up to their claims.

If you have a 7RM that works and esp if u reload no reason to buy new 7PRC. New twist, heavy for caliber high BC bullets, standard mag length and esp the factory ammo option are the advantages for the 7PRC. If u reload or have a custom 7RM it's a moot point. My 24" proof carbon barrel shoots factory 175eldx at 2930 in 7PRC. The new PRC line is just updated calibers from earlier years not making them obsolete. The advantage is in the longer ranges. If you have a 7RM shoot it. If u are in the market for 284 caliber why not buy. 7 PRC.

I agree with the comments that if you are going to hand load, the 7RM or 280AI can do about anything you need/want with a variety of combination of loads. If you are going to shoot factory ammo then the 7 PRC might be better for you. I have a 280AI that shoots very well, and feel that i dont need another 7 at thr moment.
I did recently purchase a sako s-20 in 6.5 PRC. Out of the box using factory hornady ammo we were able to stretch it out to 800m before missing thr 1000m target. Bought it for a hunt out west, because I didnt want to bang up my 264WM. Is it a 264 WM? No. Is it very accuate ? Absolutely! 3000 fps suppressed is somethjng a little different. I will try to formulate my own load. It come down to preference. Same arguement can be made for 6.5 Cm versus thr 6.5x55.
