A New Direction - Federal's 80,000 psi 7mm Backcountry Rifle Cartridge

[actionshooter]

 Advertising 3040 with a 170gr bullet out of a 20" barrel is impressive, would be a great suppressed gun, but not being able to reload and proprietary powder doesn't even make this caliber a consideration.

 Plus, I'm getting 3100fps w/ a 180berger out of a 7RM and not even close to max... I'm happy with that.

With regard to one of these being a good choice for a suppressed rifle I'd talk to whoever makes the suppressor I plan to screw on the end of one of these things first because I would imagine the muzzle pressure will be pretty high and higher then many suppressors are rated for.

yeah I’ve read some reports of Ti cans being blown up. Also read that pressures on the boxes vary pretty wildly, up to 92,000 PSI. Lots of reports about having trouble to get it to group well.

Won’t be an early adopter, but once the kinks get sorted out and the line expanded a 6mm backcountry could be neat.

With what powder and charge? Has to be over max charge!

That is a good point.  The muzzle pressure calculators suggest some rather high results for 7mm Backcountry, but those calculators are not always real world results.  I contacted Silencerco about using their suppressor that is rated for 338LM pressures, and they advised not to use it yet until they finish testing and research and development regarding the 7mm Backcountry.   So will wait to see what the various suppressor manufacturers eventually recommend for using with this new cartridge.

Ya, I think that's a solid point... the pressures they are printing are pretty high..

I don't understand how, but they say that muzzle pressure is not much different?

Their load or Mine?

 I'm not even close to max for my gun/load... I'm running a 7RM,  69.8gr RL26 w/ 180gr Berger right at 3100fps and it shoots incredible.
