I needed to pattern a 2-1/2" gun so I grabbed a box of #7 loads on my shelf and ran out to the range.
Well I grabbed too fast and was quite surprised at the loud boom and cloud of smoke, (not too mention the stink) at the first shot.
I mistakenly grabbed a box of Gamebore Blackpowder loads I got at the Vintagers for a Lefever G damascus gun.
I fired 3 rounds in each barrel. What a damned mess to clean afterwards. Hot soap and water didn't to it all, the kitchen sink was a horrorshow. Finally resorted to steel wool to get the residue out then blow with compressed air, had remove the extractor to clean the water out, then some bore cleaner and oil.
Anyone shoot this stuff regularly? I was told that Gamebore BP is particualrly dirty and some of the other stuff is cleaner?
No wonder so many old guns have pitted bores.
