Free: Contests & Raffles.
I crimp all my ammo that's run through a semi auto.
I run mine through the Lee factory crimp die. Honestly, I haven't ever done any tests to see if it does anything, but it's just one more pull of the lever.
I go the other direction - anneal every round, low neck tension to get low speed variations but then I’ve never tested with crimping.
