I have a S&W Model 544 in 44-40. The revolver was made in 1986 and was in unfired condition when I bought it a few weeks ago. I have fired 300 rounds of ammo so far. Today when I returned from the range and began to clean it I found some severe scratches on the front of the cylinder. It looks like someone took a sharp instrument and randomly gouged lines in it. After examining it I can find no explanation. Has anyone experienced this problem and how can it be corrected? Thank you. Doc
