Dyna Bore coat, gonna look that up. I guess I have had awesome luck in the barrels I have owned. The worst barrel for fouling copper was a Holloway Arms blank I had turned down, fluted and chambered for 308, what a waste of money! This barrel spewed copper out onto the muzzle. Maybe Dyna Bore coat would have saved it but I put a Douglas 22-250 barrel on the old Mexican Mauser and all was good.

Dog I rescued in January
