Rem 7.5 and cci 41 have harder cups and don't flow as much into loose firing pin holes. A cci 41 is basically a cci 450 with a harder cup rem 7.5s were made harder to deal with the flow of 17 rems. I run a lot of the cci 41s.

I've got a bunch of 41's, and never thought of that. I will try them next time I load them up.
