Been loading for my 1911's and 2011's for many years, and recently tried IMR 700X under 230 gr. lead bullets. Outstanding consistant results over the chronograph, and accurate. Used Winchester and Hodgdon powders in the past...
4.4 grains gives me 751 fps with a 9 fps extreme spread with 15 shots fired. 15 lb. recoil spring in a moth balled Les Baer custom build pistol i put together 20 some years ago. Loaded with a 550B Dillon that is even older than the pistol...Anybody else use this powder, its been a favorite for trap league loads for me for a long time...
