My most accurate loads use Bullseye, but I have also gotten some good groups using Unique and 231. For target loads I use the Hensley & Gibbs 68, 78, and 130 bullets. I do have to adjust the load depending upon if they are tumble lubed with Alox, conventional lube, or powder coated.
I really don't shoot many jacketed other than SD or hunting loads which I usually go with upper end loads and a 230gr HP. Those usually get an upper end load with AA5 or BE86.
I have two 1911's and a G41 that goes hog hunting or rides along with me while I'm mowing on the tractor. Never know when a fat hog will get up outta a tall bunch of grass thinking it's sneaking away. All shoot the same loads relatively close and plenty close enough for a critter, no matter its stance.
