[QUOTE="Batsin, post: 2897685, member: 126867"] Just a couple of comments. Military ammo budget numbers show that many more rounds of the lower-pressure practice ammo has been ordered than full-pressure. It is very likely that these weapons will mostly see the practice ammo until sent into battle. The full-power ammo would shoot well beyond the safety zone of most ranges. This will be an issue with some practice ammo as well, which is why reduced-range ammo will be used a lot. This should increase barrel life significantly. I don't think that action strength for civilian rifles will be much of a problem. Max backthrust on a bolt (and lugs) is max-case-dia X max-chamber-pressure. If you run the numbers, the backthrust of the .277 Fury at 80k psi is significantly less than that of a WSM or RUM cartridge running at 65k psi. Maintaining enough steel thickness around the chamber and in the first few inches of barrel should not be a problem. This is pretty much a non-issue. [/QUOTE]
