What is you guys take on JB paste? I've heard it's very good and very bad. Just how abrasive is it on barrels? How much use is to much? Will it damage barrels with normal use?
What about Flitz, is it any good?
Reason for asking in a good friend has a new/used rifle with a very rough bore. The rifle hasn't had many rounds through it (maybe 60-80) but it is rough. Not with rust, just rough and fouls pretty bad.
Thanks
