I've been PCing for about three years and after cleaning my bullseye gun, I've found severe leading, in the bore. I shoot a fair amount so clean every 3-500 rounds. The only difference is the powder... vampire red from powder by the pound, or prismatic coatings, can't recall and can't find the reciept.
Bullets have been cast using same alloy composition, but possibly a different batch. Sized on same equipment. So the most obvious difference is powder
I've got new bullets cast, coated and loaded up with previosly good coatings for testing... we'll see how it goes, but wanted to share my first PC failure and see if anyone has experienced this.
