I shoot 115 grain Bergers out of a 6mm Rem, on a 700 Long Action, that is throated to allow those bullets to be seated to magazine length....

With a 24 inch barrel, 1 in 7 twist, and a stiff charge of RL 19 ( which doesn't seem to affect the brass any), it will yield an MV of 3250 fps....

The rifle will run with any factory loaded ammo specs of the 240 Weatherby....all day long...
