Bore Scraper Q.
Been at this game for quite a while, and swabbed plenty of BP from barrels, but, never used a Scraper. I picked one up on a sale that was made this summer with some other things. It is brass. My question... does scraping the breech with these do any harm to the inside of the barrel ? In other words, will the constant scraping of the breech, wear the inside "finish" and make it more susceptible to gunking up ? I have no experience with them. To get into the breech, I always used the pronged patch puller with a patch, and lightly twisted it down there. So, what say yinz ?
