A number of years ago Smith & Wesson sold a product called FRICTION BLOCK. Does anyone have any experience with it? :confused:

Wow, been a long time since I've heard that. Never used it.

There has been some pro and con discussion in the past http://benchrest.com/showthread.php?69048-Friction-Block-Oil

Going back 20 years or so there was quite a bit of talk regarding itís qualities as a bore treatment often used in handguns specifically to reduce lead fouling from cast bullet loads and it supposedly increased velocity. I fell for the hype and gave it a try. It wasnít long before I got rid of it or used it up around the garage. As I understand it, itís basically PTFE (Teflon particles) suspended in an oil matrix. I recall the Teflon content was very high giving the oil a milky white color. It tended to dry up leaving an uneven tenacious white coating behind.
