yes, could not believe how long its been.Last year I FOUND fine a mark in bore 3/4 inch from muzz.about length of 370 maxi-ball.i thought it was lead but i do not think so.what caused that is beyond me .i started using the max-balls without bore butter on them at that time .before i never had ring around the bore in that spot .it does not look like lead it looks like its into rifling ..broke my heart to see that.so i used j b bore paste hoping it was lead but i do not believe it is..

what could cause that to happen 1 inch from muzz..cOULD DRY MAX-BALL CUT BORE...
