I'll check out ChemTool. A quick Google just now couldn't determine whether it is chlorinated, which can cause stress-cracking in steel. I do use Gunscrubber, which is non-chlorinated.
I like CGW, and David has been generous with his time. I've spent a ton of money on parts from them, so I think it's worked out.
I haven't shot at many things thrown in the air. It's hard to find a safe place around here to do that. I bet I'm not that good at it because my trap shooting skills are pretty mediocre. I'm primarily focused on USPSA, and being competitive at the M/GM level takes a lot of work--and a lot of bullets. But it's great fun!
