Federal’s 7mm Backcountry

[Griffbl]

Interesting...

I've no need for it, but it's interesting anyway.

my thoughts too Guy.....thank you

Looks like some gas leakage around that primer as well

the photo looks like it could be the case, (no pun intended) but no leakage. case is still airtight. Just FYI.

That's a fairly serious looking crater on the firing pin. Nice looking rifle though.

 

[Griffbl]

Probably higher than that.

looks very similar indeed to an

THE NEXT ISSUE WILL BE HAVING THE ABILITY TO RELOAD...................NOT SURE IF FED GOT ALL THE KINKS WORKED OUT OF THAT PROCESS YET

THE BIG DIFFERENCE IS SUPPOSED TO BE WITH 15K EXTRA PSI ON MAX FOR THE ADVANTAGE ON SMALLER CAPACITY CASES. NOTHING DIFFERENT THAN THE 277FURY, BUT W/O THE 2-PIECE CASE. SURE YOU CAN GET THE SAME VELOCITIES WITH THE SAME BARREL LENGTH OF THE 7BC, BUT REQUIRES A LARGER CAPACITY CASE.............WORKS FOR ME. THEM GOING WITH A 20" IS FOR THE PEOPLE THAT USE SUPPRESSORS TO SAVE ON LENGTHS.

Spot on TexasLife...that is exactly the idea....said another way, it was to duplicate a 7mm PRC in a smaller case ,and with a 20" barrel. Exceeds velocity of a 7mm PRC when both using 24" barrels...again, that was the IDEA.

My original post has now been updated with comments from Federal Ammunition AND with loading data which I will post again here. If I need to move the update down here at the bottom of this thread, please advise. I combined it to simply have all the information in one post. thank you all.

While it sounds crazy, I’d have to guess Federal has done some homework.

The idea of an 06 case making 28 Nosler speed in an 06 sized rifle sounds like something I’d love to have elk hunting. Time will tell. I heard the case is reload able so that’s a plus.

Heard there are 12-13 makers lined up to chamber them after it’s official.

Gotta admit, a 170 grain Terminal Ascent at 3150 from a 7 1/2 pound all up rifle sounds like a complete hammer, but a feather to carry. Mainly those are the ballistics that led me to the Mashburn Super, but I’m a pound heavier and a round less in the mag of said cartridge.

I agree...looks very similar indeed dimensionally to a .280 AI.

i wish they'd give psi results on their max loads per powders.

Agreed! from what i have read about Ramshot in the '06, that sounds like a promising start given Federal's data IF I were to ever load this thing....we will see what happens with Federal's replacement ammunition.

None of those are really “fast” powders. I’ve never seen load data for it before but that is pretty cool stuff. It’ll be interesting when things all get sorted out. It’s a truly neat cartridge. I’d love to have that capability in a Kimber Montana 84L sized rifle.

The Rifle Manufacturer (again, in my example Weatherby) i.e. an incorrectly cut chamber or reamer of incorrect dimensions.

I seem to remember when Weatherby started to chamber the 338 Lapua in the MarkV people were having issues with Hornady brass sticking in the chamber. They must cut their chambers on the tight side.
Hopefully the newer ammo will solve your issue.

Thank you so much. Me too. I will post results when new ammunition arrives.

I'm eyeing up a Weatherby 307 Alpine in it. I just got two new rifles this year for hunting that I never carried yet, it's hard to get a third but I am very intrigued.
