I once had a bit of a chat exchange with Hilton Yam and asked him what ammunition he prefers in a 1911 and his reply was to the effect of the 1911 being designed around round nose ammunition, and that his advice is to use bullet designs that most closely follow that original pattern. Happily, I still have several boxes of the old Winchester white box 230 gr JHP that does closely follow the ball bullet profile. They do go through everything like crap through a goose.
