Mac, what issues have you personally experienced with 220's in the 10mm? I've read internet chatter but have not experienced any issues after a couple hundred rounds of Underwood 220 gr. hardcast at 1200 fps. Nor have I had any issues with the 200 gr. XTP hollowpoint at 1250 fps from my G20.
Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
