I just picked up a STI targetmaster 6 inch 1911. Not sure what the twist is.
I was thinking of 124gr with 3.8-3.9 of Win231. I'll just try it with the factory 10 lb. recoil spring and work my way down.
I've tried atlanta arms 9mm PPC load for 5 inch 1911 and I thought it was a little to hot for me.
Thanks for your input guys. Keep your thoughts comming guys.
