As of Friday October 24, 2003, the new Hardcast lead 220gr bullets will be available from DoubleTap. I had previously thought that 1180fps was going to be the ticket, but after 1,900rds using different loads for accuracy a slightly slower load prevailed. Out of 6 different 10mm's including: 2- G20's, G20C, Kimber, G29, and a SW 610 this load is much more accurate than the full throttle load. It develops 618ft/lbs out of a stock G20, and with a B.C. of .221, it keeps its velocity extremely well!
G29 - 1069fps
610 4" - 1103fps
G20 - 1128fps @100yds - 1018fps for over 500ft/lbs!
6"KKM - 1240fps
