sometime, then do same with 230 gr jhp .45's. You will be SHOCKED at how much further the cans move with the 223. The .45 might toss them 2-3 ft, the 223's sometimes move them 20 ft or more. Underpowered rd my ass. You just have to LOAD it right, and get the HITS. When you whack big dogs in the chest with such .45's, SOMETIMES they go right down, and sometimes they run off, run in circles biting at the wound, and sometimes they just charge and try to kill you. Shoot them with good 223 sp loads, and they are knocked on their backs, and they CAN'T get up again.
