Yeah, my SW1911 prefers round-shaped ammo, too (vs truncated cone).
Just about any hardball load will work, including Wolf, which mine shoots better than Win Wally White Box Val Pack, Win White Box, UMC, Winclean, & PMC.
I found mine did not like Gold Dots, but absolutely loves Remmy Golden Sabre 230gr HP.
Yours, too, is a tackdriver? This seems to be common with the SW1911.
FWIW, I think its monster claw external extractor helps in the reliability dept. S&W did it right, Kimber, IMO, did not.
