1-7 twist too much ????

Hello there folks, my question is am getting a new custom barrel for my ruger m77 243.. I am shooting 105 bergers and A-max.. I changed my mind for 1-8 to 1-7, I think it would stabilize that bullet better than 1-8. I dont think I am over revving that round. ... what you folks think ???

    In my opinion a 1 in 8 or 1 in 9 would be better.

    The really fast twist barrels are hard on bullets (They have to start very fast and can engrave
    poorly). if you want to end up with a very fast twist rate you might look into a gain twist barrel.

    For accuracy most bench rest shooters go with a slower twist to get cleaner engraving of the bullet.

    If you were shooting something very slow like a subsonic the 1 in 7 would work.

    Most of the 223 rem shooters tried the 1 in 7 and even the 1 in 6 and went back to 1 in 8 for the best accuracy.

    Just my opinion

    IMHO 1-8 is plenty of twist for the 105's.May even work with the 115's depending on temp and barrel.
