Are the BR primers better than say the standards. I've been using CCI BR primers and not tried anything else. Just curious. Thanx

CCI primers as I see it.

The BR4 undergoes stricter quality control.

The 450 and BR4 should be your go-to primer if you are loading hot because they have a thicker cup.

Thanx thats some great info. A good chart to keep on hand.
