I'm in the process of building an AR. I know I will be installing a 16" CT legal barrel, but I am not sure about the twist rate.
I know the 1:7 is better for stabilizing the heavier 62 grain bullets, but how will it work for 55 grain bullets? I have a good supply of both 55 grain and 62 grain ammo. Would the 1:7 work well, or should I stick with a 1:9?
Thanks
