I started out with an Avenge X in 25 cal, because the shop didn't have it in 22 cal. I'm extremely happy with my choice. I decided to purchase a 22 Barrel Kit and decide that I would clean it well before putting on the Avenge X. So for after scrubbing with brushes ans well treated bore cleaners, I still get an awful lot of black on the patches. I looked at the bore with my scope, and it still doesn't look clean. Has anyone one else have this problem getting a new barrel clean before shooting it. The 25 cal was not a problem at all, but this 22 has me concerned. Over 30 patches and they still show sighs of fouling. The bore finish is really dark and rough looking.
