Just a bit of a wild idea.
I've been trying to decide if my 9tw Pac-Nor barrel would be better as something faster than a .223 Reminton.
22-250 35degree shoulder
or something wilder.
Has there ever been a 22/30-06 ?
22-243 Ackley 40 degree
22-284 aka .22 Tejas
Shoot an 80 grainer at warp speed and kill stuff at very long ranges gun)
Increased velocity will help to stabilize a bullet...Not a lot, but it will help some. So you might could get away with a little bit slower twist with the kind of velocities these calibers will be producing.One thing to note on "heavies" is that the barrel is a 9 twist. So ~70 grains is the limit.
