How bad is the 7 backcountry?

[southpa]

i haul and have been hauling since '80. granted the turbos and electronics give it a slight edge, but mpg is a joke. my '81 454 (about 390hp) , turbo400 and 3.73's gets me 14.7mpg @ 85mph towing a gcvw of 30-35k into a 25mph headwind. not doing that with a diesel. btw there's nothing electronic on it besides the distributor. my '15 model 3500hd doesn't get anywhere near that (5-6.5mpg). 460's are horrible engines anyway, especially on fuel mileage. $ per mpg goes to the gasolines. torque goes to the diesels only if turbo'd.

What are you even talking about

Put the bottle down my freind lol

I don't know, I think this will open the door to new case materials for the future.
I personally see this as the "future"
Imagine new case materials that will allow the regular .223 or .308 rifles we currently own to be able to reach 80k psi or possibly even higher.
I foresee brass going by the wayside in our future.

At least for bolt rifles, you can run the 277 sig fury through a 308 win die and go shoot it in your 308win rifle now.

This^^^

But it's not easy to find a 277 Fury barrel, there's one place that was making them recently. Because of the cost to replace an AR barrel, most people don't tend to chamber them for themselves, they just replace them.

Those specialty items tend to be costly on the AR platform, same with any long action cartridges as well. There are a couple long action ARs, but very few, the AR market is mostly mini-action and short-action.

For me, I would want the 277 Fury in a bolt action. That's been true for a long time. Yet another case of the IBM salesman sitting at the end of the bed telling his wife how great the sex is going to be when he gets back, but he's sorry he doesn't have more time before he leaves... The Fury was crying wolf for civilians long before the Backcountry was conceived...it's not clear if the military is using it or not, testing with it, or what is going on with 80,000 psi. We all know how slow the military is upgrade, and what we're seeing with 7BC or Fury is not what they're known to accept, let alone upgrade to.

I'm not sure if there's anything truthful these days...we can't believe anyone and everyone is quick to tell us they can jump over the moon.

You can do it with any .308 based cartridge. I do it for my .308 & 260AI.

I have even done it for my 22-250AI but it wasn't real easy.

With your 260ai, do you still have to bump the shoulder back? Basically... does the fury have a shoulder forward or back or a typical AI cartridge?

You can order a 277 fury pre-fit and have it in a month or 2.

This is true, but I don't think you're willing to take the chance on 7BC just yet, are you?

If it lasts and makes some traction, maybe next winter project. Just a barrel and gunsmithing. I have barrels. I can fit barrels.

..and my 6.5 Creed will out-pull a 7 BC and smoke a grizzly at any range with a whole lot less powder... (yeah, it's got a turbo)

Just ribbing you bro.

Yeah, that's a possibility. Numbers for LR-308 dwarf the bolt actions though. I have though if you had a barrel for 277 and a barrel for 8.6 blackout, that's pretty much all one would need. I don't have an 8.6 blackout in a bolt yet.

But what has the Fury done? Has anyone got near 80,000 psi ???
