When I first started shooting BP I tried the TC bore cleaning stuff too, IMO its crap at best. I still have 3/4 of a bottle around here somewhere thats about 10 years old, I saw it somewhere about 6 months ago and thought "that stuff needs to go in the trash" then it got lost in the shuffle again. I'll back up what the other guys are saying, soap and water does best and it's the cheapest. Bore Butter is a good bore lube though, but its only one of many options. I still pick up a tube here and there when I see it on clearance after deer season.
Beware the man with one gun, he knows how to use it
