i wish i could find that article on barrel wear. i guess author was saying that 10,000 rounds is what you would get with 2f. he then said with 3f you would get around 3,000 rounds. i too am curious on when you started having bad shooting with your hawkins and what powder, 2F or 3F. i may have just got scared out of using 3F.so, i guess we have to lower the charges if we use 3f,which we do anyhow.i am trying to find that article, i swear i put it under favorites.
