Use one often in my guns and have had no problems. Be sure to inspect the brush carefully before and after use to make sure the loops do not break. I think if one was to run a Tornado brush thru the barrel with a broken loop it may actually scratch the inside of the barrel. Not that anyone wants a scratch down their barrel, but it wouldn't affect the performance one but if it did have one. JM2C--Matt
"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
Hey pat read v-10 post, and check out the link. If your barrels arent any harder than what he is advocating, I'd sure hate to shoot one of your guns. Read it all before you comment and maybe be a little open minded Huh?
