Forgive me ...I didn't do a forum search first and I'm asking my question anyway...
My S&W 500 is made from a different, much harder/tougher, stainless steel than other S&W stainless steel guns. The manual says NOT to use ammoniated gun cleaners on it (CR-10, Sweets 7.62, etc). All of the gun cleaners that advertise the ability to clean lead out of a gun have oodles of ammonia in them ...
Here are the methods that I'm aware of...
1. Using an ammoniated cleaner such as CR-10 or Sweets 7.62 (a few bucks)
2. Using an electrochemical/electrolytic like Outer's Foul-Out III ($160 to get started, including supplies.
3. Using a Lewis Lead Cleaner system ($50+ to get started ...and only goes through .45 caliber, but maybe the .50 caliber rifle cleaning adapter would work on my 4" 500 S&W?)
4. Mechanically cleaning with pure copper brillo pad in various ways (doesn't clean the grooves in the rifling?)
What else is out there? What works entirely well yet doesn't break the bank? Are those ammoniated cleaners OK in my S&W as long as I follow the instructions on the bottle and limit exposure ...or is there cumulative damage that I should be aware of? How should I get the lead out!?
