Many years ago I found that a good 200 gr. lead semi wadcutter at 850 fps or even less can do alot of things well while being cheap to shoot. It lacks nothing as a target round, or a small game load.
I suggest you try any of the faster powders, varing the charge by .3 grs. until your gun shoot them accurately. Don't be surprised if even a service grade 1911 will put five into 1.5 inches at 25 yds. The trick is to use good brass, and find just what the gun likes. E
