The rifle would be based on a stainless Remington M700 long action, and probably a 24-26" fast twist 1:7 barrel to shoot the heavier 105 to 115 grain bullets. The rifle would be used primarily for fun, target practice, coyote and deer hunting. I know the .243 has better (Lapua) brass availability but a little less powder capacity. The pros for me of the 6mm is that I have quite a bit of Remington brass on hand, reloading dies, and it should yield a little more velocity. I'd like to hear other's thoughts and opinions on this. Thanks in advance.
I would go with the 6mm Rem also because you are familiar with it and have all the stuff to
If you intend to shoot the 105+ bullet weights you will need to increase the twist rate.(The old
factory barrels had a 1 in 12 twist and that is what killed there popularity compared to the
243 Wins 1 in 10 twist.
I would recomend a 1 in 8 twist that would allow you to shoot any bullet weight without over
rotating lighter bullets.
A quality barrel like a Lilja Stainless will also help the velocity and cleaning.
