Thread: making the change from 223 to 6.5grendel (maybe even 6mm arc?)

120 gr at around 2400-2500 fps has the grendel in the same space as the parent 7.62x39 and that's no slouch. There may be a bit in it from higher bc due to a longer bullet but ammo cost and availability would make me keep the 223 and maybe get a 7.62.
