I'm using silver bear not wolf, think it has a zinc finish on steel. Imagine some laquer on them also. I've cleaned the chamber using a brush and solvent. Just used a size that would hit the chamber walls. Haven't had a chance to head back out with it. When I do, will start with a clean chamber, action, barrel, and use brass first. If no jams will go to silver bear then back to brass for a bit and report on here. thanks
