My pleasure to have helped you.
Iosso Bore Cleaner is wonderful stuff. I was given a Marlin Model 410 lever-action shotgun some years ago and thought the bore was sparkling after I'd cleaned it with a brush and Hoppes No. 9.
Then I ran a tight patch with Iosso Bore Cleaner on it, through the bore.
A patch brown with rust came out! A couple more passes and no more brown!
A look down the bore revealed it gleamed like a new Cadillac!
It's not often found, so when I do find a store that stocks it I'll buy three or four tubes. Wal-Mart used to stock it about five years ago but haven't seen it since.
To order, call Iosso of Elk Grove, Illinois at 847-437-8400.
And noooo .. I don't own stock in the company or know anyone who works there.
