A man I know gave me some brass as he does not reload. the brass is S&B .44 mag. When I resized it I noted that my die shaved off some brass on 1 side of the case about 1/2" above the base. Every 10 case sized I had to remove the decap pin and clean out brass shavings from the die. I had never seen this and it doesn't happen on any of the .44 mag brass I reloaded before. I'm wondering if there might be a problem with the mans revolver.
