For 40 years or more, the ONLY SOLVENT I ever used was Hoppe's No. 9. Never had any problems. Then I found out I had been cleaning my guns "wrong" all those years when I read an article by Seyfried in the RIFLE Magazine. So I bought a bottle of Shooter's Choice which I have been using with complete satisfaction ever since, except that bore brushes have to be washed with hot, soapy warter right after use with Shooter's Choice, or the stuff will eat up the brush!!

Hoppe's DOES remove copper fouling, but it is a matter of weeks, not minutes, for it to act on metal fouling!

The more rounds you put through a rifle, the harsher the solvent you need to use.

Old Harry Pope once said that more bores are ruined by a cleaning rod than any other way. I've heard that there are contemporary gunsmiths who believe this also.
