A while back I bought an abused, homeless Taurus 94 and nursed it back to health, or so I thought. Bore was shiny and clean, cone looked smooth. Yesterday I shot around 100 rounds of CCI ("AR tactical", jacketed 375 pack). Accuracy seemed OK but I was only working on my double pull at ~8 yds. But when I went to clean it, I found semi-circular lead flakes again! Should I expect this or is there something potentially worse going on like misalignment?
