[QUOTE="Bob Wright, post: 3062436, member: 104363"] If it's "Iosso metal polish" it's not aggressive enough to change bore size in our life time. It's very fine material. Bore laps like what used to be used to lap out tight spots in rifling were done with a lead cast lap and valve lapping compound of various grit sizes. Today's barrels are getting so well done, that process of hand lapping is pretty scarce today. Maybe Tubbs will help it out a lot faster. [/QUOTE]
