Federal’s 7mm Backcountry

[gerry]

Federal apparently has been working on this for 6 years, I'm sure they have figured out how to make this work. All the companies offering rifles have confidence in it too or they wouldn't have jumped on board It sounds like the reloading process will be a bit different from what we're used to so it will interesting to see what they come up with. This potentially could be a big shift in cartridge development and this may be the future.

It could be.

Time will tell one way or another. If this works and they make a 270 version I would be very interested.

Iron and steel alloys definitely are an endeavor in chemistry and physical science. I used to pour camshafts and crankshafts in a foundry. We would mix and melt the alloys to 1530 degrees Celsius and deslag it. Pour it into the molds at 1430 Celsius. Then heat treat them at somewhere over 900 Celsius for 49 minutes. At that point they would go into hydraulic pressed dies to be air quenched and cool. Then if they passed to machining.

The chemistry of the alloys are very sensitive. If it’s off in the slightest they were scrapped. You could also tell the chemistry was off by tapping them with a small brass hammer. The sound was distinctly different if it was out of spec.

For camshafts there was a lot of things that went in the mix. We used in different quantities, red pig iron, grey iron, chromium, copper, magnesium, and carbon to get the right alloy. I’m sure the cartridge case is more complicated.

LOL, I was kidding to begin with about using the bottle jack to size cases, but it’s looking more and more viable. Sooooooo, I may as well have fun with it

Putting in my order now. I want a hydraulic progressive press, with an electric pump so my arms don’t get tired pumping the jack. Pure chromium sizing dies so it doesn’t scratch those new cases. You’ll cry if you buckle a shoulder on one of these!

Depleted uranium projectiles to combat bullet failure. But, on the up side neck tension will probably be firm enough that you don’t need a crimp die. OH, and I’ll need a hair tie to keep the braids out of my eyes during my annual 3 shot group. Lol.

but Savage is dropping them today at KyGunCo for $558

I think it’s because of that butt ugly stock

Joe your points are all valid.

It won't for long when some people lose facial parts from exploding rifles. Too much pressure for most of the guns being manufactured today. Only rifles I'd trust with that much power are double rifles, Ruger 1s and Mauser style actions with heavy bolts to protect you.

I am all for innovation and have thought about a 277 sig fury. I am not sure about this Federal version yet. I certainly wouldn’t buy one until saami certified and bugs worked out. Both Sig and True velocity have their 80k 6.8 rounds saami certified so that is not new so what is holding up? I am surprised Federal and Savage are dumping product before Saami unless they already have it and not published. Sig and Seekins both redesigned their rifles for the higher pressure. I would also be leary of any action that has not done same. Proof rounds are to weed out any manufacturing defects not prove an action is safe to handle higher pressures over many firings.

After watching this stuff for over half a century, I will make a prediction up front: This caliber will fizzle out fast.......

 

[Blkram]

My main question is how is this cartridge going to perform on game?
Will the bullets hold up for proper expansion and penetration?
How much bloodshot meat will there be?

If it is just for flatness for target shooting, that is one thing...but you know someone is going to take it hunting...
Will it penetrate like a lazer and not expand (similar to a solid/FMJ bullet), providing no real tissue damage on its way through the animal, where if it does not contact the spine in front of the shoulder (or brain) and provide an instant kill, is the animal going to run off a fair distance and potentially not be recovered, due to lack of a blood trail, and many new hunters not willing to take all "reasonable" efforts to recover their wounded animals? (a reality becoming more frequent in this day of the instant gratification trend)?
Or, will it just shrapnel and not penetrate at all? (Jus as disastrous for lost game with wounds that will cause suffering and death at a later date, and the animal potentially not recovered.)

We are already seeing way more animals shot at long ranges, with match bullets not designed for hunting, that are not being recovered because the hunter cannot locate the location of the animals where it was shot, and are not following up to recover the animal. Just ask your local game wardens/conservation officers; they are finding this way too frequently, and even they are having troubles determining where the hunter shot from while investigating.

So if this round is running about the same speeds as current offered rounds, is there cause for concern about bullet performance. a 100gr BT dosent care if it comes out of a steel case if the MV is 3100 fps, seems like a 25-05 to me? Maybe not....? Dosent matter, I wont be buying a bunch of new reloading equipt to do it, no matter how miraculous it is, CL
