Found this today cleaning my new 629 44 Mag. Appears to be metal flaking off inside the barrel, only seems to be in this one spot but they are deep. Gun has less than 300 rounds and has only ever fired light handloads less than 950 FPS using copper plated bullets. Tried calling Smith but I guess they shut down early for the holidays. My local gun smith said he's seen this before with stainless barrels but its rare. Anybody ever see this??
