[QUOTE="CV355, post: 16039695, member: 181885"] If we want to get extremely technical, sure there is a difference. Low Velocity .22LR: 2.6g @ 320m/s vs .223 (SS): 3.5g @ 330m/s.. ~130j vs 190j Compared to a normal 9mm ~470j Compared to normal 5.56 ~1850j Can you load subsonic 223 or 5.56 and it be lethal? [b][i][U]Absolutely[/U][/i][/b]. But the margin of calculation error and variation puts you in roughly the same territory as .22lr. It's a massive reduction in kinetic energy no matter how you look at it. The only way to get kinetic energy back up when at or near subsonic speed is to increase mass. I'm not saying that a competent reloader will always wind up with squibs- I'm saying that the risk is there because your working pressures are vastly different. You and I both know how hard it is to press a lodged bullet out of a barrel. [/QUOTE]
