I just saw an article extolling the virtues of the 6mm ARC over other m-16/ AR-15 cartridge options.
It has a bullet weight of 108 grains which is better than the 55 gr of the original 5.56 and
a BCF of .520 for 1000 yard supersonic flight and lower wind drift. I did not see much on
the terminal ballistics of it. Will it punch through hard stuff or just fall apart? Will it tumble like the
original M193 ? I was thinking the 6.5 Creedmore or something similar would be chosen for an
slightly up-sized weapon system and we would get away from the AR gas system to a short stroke piston
style action. I personally like the 6.5 bullets in the 120 to 155 gr range at velocities that keep the recoil
comfortable.
What are your thoughts on this development?
