"I don't see that a T-brush will do anything that a regular phosphor-bronze brush won't do, and cheaper"
I use to think the same thing until i had ran just a bronze brush(no solvents) thru my gun at the range. A friend said, "tell me when you think its clean". After i thought what looked nice and clean, he ran his Tornado thru the barrel. I was amazed at what came out that a brand new bronze brush hadn't touched. Sold me. That being said, i use one only occansionally. I normally use my bronze brush with a patch on the end with solvents first and then procede with my cleaning process.---Matt
