I have about 1000 rounds of brass.. All range pick up, once fired as they were crimped. LC, Wolf, Federal, Norma, Hornady, PMC, Starline, Remington, and Winchester that all weigh right at 92 gr + or - a grain. Most of it is LC or Federal .

Then I have some CBC brass that weighs 101 gr and some USA A and GFL brass that weigh 97 gr.Why would that CBC brass be so much more? Would it be 5.56 brass that is thicker in the head?

More curious than anything. I don't plan to use those three head stamps. If I do,will keep separate.

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
