Bob had a handout of cci primer energy listings..
My google-fu is not jedi level and I can't find it as a link..
I'll have to break out the russian space pen (pencil) to post it..
It was interesting the diffrence in small rifle and small rifle magnum energy (brisance)
It was less in the large rifle and large rifle magnums..

The further I get down the reloading rabbit hole the more questions about things I did not think about earlier I get.

I guess that is what makes it interesting.

All this started with a peirced federal primer in a warm 223..
Just trying to find out why..and the floating firing pin on the primer in a ar thing..
