Yeah Mark, I was using brass brushes but the guy I bought the Sweets from gave me a nylon brush which helped. Still, the nylon brush gets dirty and leaves "false positives" as well so now I'm just dripping Sweets down the barrel (with a stopper on the other end) and wiping it dry; it's working like a charm. I guess whatever method works best... lol, It's taking a long time but considering I haven't given this rifle a proper cleaning in 6 years over 200 rounds I kind of had it coming!
As it turns out the purple wasn't a big deal at all. It just started coming out much darker after the first few patches and is now slowly lightening up again.
