Thread: CCI BR4 vs CCI 400 primer’s

Yeh ,

I’ve been doing that , since someone mentioned it .
The replacement spring will be here soon and then I’ll try shooting the BR4’s again.
I shot some load development loads again yesterday with the CCI 400’s - 25 rounds in total without a misfire, but the indentations on the primers are still weak .
The new spring is supposed to be a bit stronger so hopefully that will get things sorted .
