I use Lapua brass straight out of the box. Load and shoot. I always get great performance doing it this way.
Why anyone would trim new brass before firing it, I cannot comprehend. .
I've gotta be missing a big point somewhere, but I frankly don't get why anyone would buy new brass, unless, of course xF isn't available?
Seems to me you pay a hell of a premium for that first shot, after that its xF (and probably improved by you) anyway.
What point am I missin.
