Everything I have now is 1/9 or 1/10 and they do well accuracy wise.. we use M855 and 62 to 70 grain HPs and these twists do great
But I am trying to build my gal a new M4 type carbine and the only barrel that I want and that I can find is out of stock in the 1/9, but in stock in 1/7 twist
What to do? I hear the 1/7 burn out faster, is that a realistic issue? Experiences?
