I load all my 45acp ammo using TrailBoss. I load on a progressive press and I know that loading with TB cost a bit more, but it's much easier than trying to visually determine a correct powder drop when the load is a rabbit fart of 3.8gr of something or something.
I shoot these from my Springfield 1911 and have never met a steel target that TB won't knock over.
And......the smell after 30 or more rounds is pretty pleasant!!!
