G,day
Need some help, a dear fellow BP shooter passed,at his wake his non BP friends fired his 40/72 FBW as a mark of respect,did not clean it and stored it ,it is a ss barrel.On inspection a white powder came out on a mop when passed through the barrel. Haven’t had a chance to clean fully as it is with a dealer.? Would the barrel be toast after such action? I know a chrome moly would be!!
Cheers Mal in au.
