RE: Barrel Cleaning
You won't have any problems as long as it gets cleaned at some sort of regular interval. I personally clean my barrel during range sessions about every 20 rds with just solvent and patches. Then when I get home I clean thoroughly and oil it. Before shooting again I'll run a wet patch followed by a dry one. After the last range session before rifle season I'll verify zero and clean it, then fire 2 rds and that's how it stays until after the season.
