Heads up on potential LP 45 ACP issues.

Try the Lee Autoprime.

I've yet to find a case I can't prime with it, and without any trouble. Even the rare one with a crimp.

Crimped primer mil .45 brass is extremely rare, and AFAIK not being produced except possibly for special runs. Simple, we and almost no one else uses full auto SMGs anymore like the M3 or Thompson or the UZI and the Ingrams. No reason to crimp the primer if not going full auto. So the odds of finding any on a range (except those with a special function and those aren't open to the public) are very slim.

The ones I don't like are the Seller & Beloit brass, no taper/lead at all on the primer hole and if not lined up perfectly on the Dillon it just won't go unless you crush it (which I won't ever do). If I see any of that brass it goes in the scrap brass jug regardless of how new it might be.

Funny, I use RP for throw away brass at lost brass matches. It is too thin to reliably hold a 0.451" plated or jacketed, I get setbacks. I reserve it for lead or coated lead bullet 0.452".

I use the U die for sizing my Remington brass.
All brass the same : one die for all.
