Sure helps with cleaning too.I started powder coating two years ago. I cast for 45-70, 44 mag (rifle) and 30-30. Can't speak for others but PC has been an overall improvement on all three.
My grandsons 94 shoots a pc Lee 180 grain GC sized to 309 hands down more accurately than any factory or handloads ever shot with it.
My Marlin Cowboy 44 mag shot a full tube of the powder coated bullets and there was only a little carbon to clean out,NO lead!
