stronger bolt material for high pressure loads??

[LRRPF52]

Titanium but I think there needs to be a limit. Something will give or fail with all the pressure and then what?

Are you serious? Titanium? You're doing this to torment me, I know it.

OP: If you call 1100yds still supersonic at sea level with a 123gr A-MAX from a 16" barrel handicapped, then I guess you could step up to a .260 Remington.

My 22" .260 Remington AR10 will push the same 123gr A-MAX to 2915fps. At 200yds, it has slowed down to the muzzle velocity of my 16" Grendel, so 200yds of performance loss.

My 16" Grendel with scope and magazine weighs 8.6lbs.

My 22" .260 Rem is 14lbs.

65k psi is .270 Winchester territory, and about 2/3 of the primers on the market will crater before you even hit 60,000psi. How far would you like to stay supersonic with a Grendel, or is it only about having more muzzle velocity for the sake of it, just to say, this thing cranks out at 2700-2900fps!

I was in the same boat years ago, until I shot my little 16" at 1200yds. Now I look for loads that have lower pressure, with an efficient powder that burns ideally for my gas system length, or I just shoot the Hornady 123gr A-MAX load, which is what I shot to 1200yds with.
