I'll put in a plug for the Outers Foul Out III--I've never gotten more copper out of a barrel than I have with that reverse-electroplating system, and it's not THAT big a pain when you get the routine down.
I've fired more rounds through my Astra 45 than any .45LC in the family. I've used the Lewis, lead-away cloths, and good solvents. But, I was kind of curious as to how the Outers with the lead-removing electrolyte would work.
CHUNKS! HUGE, BIG, CHUNKS OF LEAD!
I'm still stunned.
On the Surplus Special, I ran Wipe-Out in that barrel--it'll turn bright blue in the presence of copper. It didn't. Between that and Kroil penetrant, I have clear shallow rifling on a slightly-misted barrel. Shame the number on THAT doesn't go with anything else on the gun, but it certainly looks and functions well enough.
Of course, I still need to... What's the word? SHOOT it...
Best!
