The latest greatest Federal Cartridge

[CMP70306]

Nuff said!

And 7 BC is doing 3,000 in a 20" so the extra 140 fps of the 7 BC gains me what exactly? An extra 100 yards I can't use?

And let's be honest, if you hate the PRC line now you are also going to hate whatever high pressure version Hornady comes out with next anyway.

I'd like to know what the fps is after you get it dialed in and have a 16" barrel on it. Both you and @southpa make some good points, but you just said you have one, but it's shooting 2860 in a 20" barrel... The video was getting close to 3000 fps with a 16" barrel. If I had the stuff to reload that today, I may very well consider it, but how could one do that if we can't reload for it? Do you think it's possible to eek another 140 fps faster and remove 4" off the barrel as well? Understood it's the first load, but still...

EDIT, to be fair, the Hornady site does have some loads at 3000 fps for a 175 grain ELD-M, however that's with a 24" barrel. That means you believe you will get the same fps with 8" off the barrel? That's a pretty big magnum.

My goal for this rifle was to land my effective range somewhere between the 650 yards for my 20" 30-06 shooting the 178 ELD-X and the 1000 yards for my 26" .300 Win Mag shooting the 225 ELD-M. I thought about going shorter than 20" but being my first foray into the 7mm caliber I decided to be conservative about it plus it reduces the risk of suppressor incompatibility since there are a bunch of good titanium cans limited to 18" to 20" on magnum cartridges.

I'm sure N560 and RL-26 would get faster speeds out of the 7 PRC but that extra 23% pressure ceiling on the 7 BC makes up for a lot of difference in powder capacity and about 300 fps over similarly sized cartridges like the 280 AI.

In "half heartedly" following this thread, I was just struck with this thought.

With so many having an aversion to recoil……I must assume that this additional velocity comes with some increased recoil. Yes it can be mitigated with brakes or suppressors……but, not everyone "swings" that way! memtb

Theoretically but at the same time you lose recoil due to 10 to 15 grains less powder so recoil will end up being somewhere between the 280 AI and the magnums

"You do know" that 2920fps is faster than 2860fps...., 20" is longer than 16"... and the case capacity of the 280 is 67 grains while the 7prc is 82.....

So it's substantialy shorter, has a substantial amount LESS powder and still outperforms the 7prc....imagine if the 280BC had a 20" barrel....with those pressure it might hit speeds the 7prc could only imagine...or wait, it already has.....

And 7 BC is doing 3,000 in a 20" so the extra 140 fps of the 7 BC gains me what exactly? An extra 100 yards I can't use?

2860 is slower than 2920....
20" is longer than 16"....
280 case is 67 grains 7prc is 82 grainss...
Put down the bottle man hahah.

And how are you going to tell me what I am and am not going to hate? The 7prc is a joke IMO. It does nothing more than sell to dong dongs who argue that it does more when it doesn't. You drank the kool-aid. It's all good. You can like what you like that's not the premise here. I truly am glad your rifles are doing what you like. But just because you put lipstick on that pig doesn't mean we all think she looks pretty cuz she ain't. It DOES NOT operform what the 7bc is already putting out.

The high pressure rounds are interesting. I saw a youtube of a guy shooting the 277 fury out of 16" Sig Cross and getting near 2900 fps with 150 accubond hybrid factory load. So about 22" with suppressor. That would make a handy hunting rifle without sacrificing ballistics and with a 308 sized case to boot. That said I am skeptical on the full steel case of 7BC and accuracy. The hybrid 277 case seems a better mouse trap. In either case I am skeptical that you don't need action designed for the cartridges for the higher pressure vs any old action. Sig and Seekins both made a new beefier action for ex
