Many of us who shoot 200 gr. LSWC in Bullseye competition ( conventional outdoor pistol) use a load of 4.2 to 4.4 of BE Powder. In a match wadcutter 1911 pistol, 2.5 inch groups at 50 yards are very doable from a Ransom Rest. I am talking about pistols with slide mounted UltraDot 1- inch red dot sights. Unlike rifles, 1911 pistols seem to benefit from a larger jump between the bullets bearing surface and the rifling in the bbl. Seating .45 ACP bullets right up to the leade is counter productive in my pistols. Best crimp for me is .468-.470 inch. OAL varies , but the amount of shoulder protruding beyond the case mouth is 1/64 inch. When I start a new lot of reloads, I stop after the first five rounds to make sure they will load into one of my Metalform mags without interference or drag. To check your loads against a Gold Standard, shoot some groups with Atlanta Arms and Ammunition's best match ammo, or Federal's Gold Medal Match.
Good shooting and keep experimenting until you get what you need for your sport. There are so many variables to work with, success will come with persistence.
