I have three Damascus barreled side-by-sides. I use RST 1125 or 1150 fps loads in 2.5" 1 ounce Lites in all of them-- a Parker 12ga. PH 30", an LC Smith Grade 2 12ga. 30" and a LeFever 12 G 28"-- all of them have good bores free of pits or fouling, and I clean the bores with a brass brush and then a swab with Hoppe's after shooting them- if yo9u were reading the bores on these shotguns and didn't know they were Damascus barreled, you might think you were looking down a set of Nitro Proofed steel barrels as well. Just clean the bores of your Damascus barreled gun(s) as you do your others--
