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.

I just don’t trust them. Copper cup primers aren’t designed to consistently operate at this rounds pressure. An unmodified factory rifle, with factory ammo, and a mallet is needed to open the bolt. It’s a 80k psi SAAMI max cartridge. What do you suppose an overpressure round is running that will lock the action with a steel case? They are too close to redline for manufacturing mistakes not to be very dangerous. Also, there’s no way that Federal isn’t going to downplay hiccups. They have too much skin in the game. The public looks to be the test bed for this new hot rod round. Twist a hot rods motor tight enough and it will let go. This is just my opinion mind you, I’m sure many may disagree.

Edit: Food for thought. A 125% proof round is 100k psi, and that’s not locking the action during proof testing. That’s a LOT of pressure to have 3” from your nose.

Weatherby actually had field testers running this caliber for over a year on many different hunts, in many different regions before they offered it on the open market. Federal supposedly has been testing it for roughly 3 years. It is the first major change in the rifle word for many many years, so the skepticism was expected. There was a time that guns moved from a low PSI to a 65k with their rounds, I'm sure every one thought they were going to blow up then, but as is everything we do today, the limits were pressed, advancements were made in design and it became the new normal. I'm not concerned what so ever with it at this point.

I don't think the public is the test mule here. That would be a major flaw in R&D and could easily crush any brands reputation if an error or mishap would occur, especially if it resulted in injury.

From what I understand the action is different than what is in our guns today, but the cartridge's case is supposedly the biggest factor in the new pressure limits. In all the testing and trials I have read about on this cartridge, I am actually excited to get my hands on one.

Since we are not allowed suppressors here in Canada, a 7 magnum with a 20” barrel has no appeal for me.
I have been perfectly happy with the 7mm Rem Mag’s performance.

I had no desire for the STW and would not have went there except that the rifle, a customized LH Sako for $800 that weighed 7 lbs bare, was a steal of a deal that I couldn’t pass up when I saw it. It has become a favourite, and its barrel is a bit faster than normal, producing 3222 fps with 160 gr ammo from its 24” barrel. It is also the most accurate rifle I own. I have taken more game with it than any other.
Is it perfect for everything? No, but it has worked on a wide variety of game over the years. If I need extra velocity and a flatter cartridge, this is tge rifle I reach for, as it is proven, and I have a good supply of its preferred factory ammo that should last me the rest of my days.
Yes, the 7 BC is interesting, but I do not believe that I will be getting one.
