ah, the 10mm...
i have a 200grain pill doing at least 1200fps out of the glock.
Momentum=Mass x Velocity. So, your 200gr bullet multiplied by the 1200 MV gives you a momentum number of 240,000 (or 240, after knocking off the last three zeros).
An average .45 ACP is something like: 230 x 850 = 195,500 (or 195.5). If you can squeeze MV up to 900, you get: 230 x 900 = 207,000 (207).
A 40 S&W seems to produce its best numbers with 180gr bullets. 180 x 1050 = 189,000 (189).
I once saw a guy shoot pins with a 45 Win Mag. With his 250gr bullets at 1250, his momentum was 312.5! But, after 2 matches he stopped using it, because his hand was hurting. It did move pins though...
