I don't like this statement, "When properly applied, it forms a low-friction coating on the surface." For me you would be better off with allowing the wax on your 22 bullets to do their job. I have found with my 22LR that I have to shoot about 10rnds on a clean barrel before it settles into its one hole groups at 50yrds.
I personally haven't tried it but one of the other members here has used it on a couple of used Senderos that he bought. He speaks highly of it. Last time we discussed this he was getting some info together to post a thread on it. Maybe the time has come???
