[QUOTE="MontanaRifleman, post: 351843, member: 11717"] Mike, I agree in that I would never polish or fire lap a lapped custom barrel. But with some rough factory bores a product like KG2 *might* be helpful. It's true, there's not much info on KG2, but it is supposed to be less abrassive than Tubbs. In the case of a bad fouling rough bore, I dont think there's much of a risk in using it. If you have a rifle that shoots the same POI first shot after a thorough claening, as follow on shots, that's great. My rifles don't do that. Their POI shifts until they get a few foulers through them. I suspect this is due the characeristics of the bore changing from bare metal to copper and/or carbon layers being laid down. It's not really a matter shooting groups, it's a matter of the POI shifting. Once fouled, cold bore shots should be on the money, but a clean bore shot in my rifles doesn't track the same as fouled bore shots. If a cold bore shot from a fouled bore lands off maark, it's probably related to a bedding issue. [/QUOTE]
