welcome to the encore club!! keeping it clean is the hardest thing for a new shooter. you have to clean after every session at the range or hunting. you cannot leave it dirty. it will rust out even with t7. my sugesstion is to start with pyrodex. a little easier to find groups with, and if your encore gets the crud ring with t7, pyro eliminates that. my encore has the 25 acp conversion, and at the range last sunday, I keyholed the pr 175 gr .357, kept the 275 and 300 under an inch over 100 gr of select powder. ask any questions at all, we're all here to help.
