So, went up to Brownells site and read this "Learning Lesson" on rusty bores. ht tps://www.brownells.com/aspx/learn/learndetail.aspx?lid=10705 I do have that stainless steel sponge here, 080-000-321, so tried it in that 7x57 bore. Wrapped up a section of it like the article shows - did half dozen passes. It definitely did slice off a bunch of crap from the tops of the lands - still lots of crud in the grooves. Ran a couple patches with RB-17 gel and left it soaking. My plan is to try to flush and get clean patches coming out as is, then go in with bore scope to assess what is going on.
