I have been shooting mine today , a real pleasure to shoot . I had to firelap the barrel . I have never encountered this before but there was a tight spot where they roll stamped the side of the barrel , and of course the usual spot where the barrel joins the frame . Today , it is very very accurate and the barrel after about 100 rounds of cast is clean as a whistle . I only have one but I shoot it " a lot " from mild to wild . I cast my own and size .411 . Had to buy that size of die from Buffalo Arms , special order . regards Paul
