looking at getting a Stainless bull barrel AR in .223 for target shooting just not sure which way to go. First 16" - 20" Bull barrel, Then there is twist 1:8, 1:9, 1:10 twist without reloading which I'm not ready for & factory ammo in 45gr. 55gr. & 62gr. What would be the best option that will work with different bullet weights. Hope this makes sence.
