Moly Coating bullets for handloading

Does any of you handloaders moly coat your bullets? This has gone back and forth in the handloading forums for years. Some pro and some con.

I moly coat (two hours in a tumbler) mostly everything I load. My reasoning for this is I shoot many vintage (and expensive) rifles and want to protect the bores as best as possible. I have found that pressures can be slightly increased because of the friction-reducing quality of the moly when the bullet leaves the case and squeezed into the lands of the barrel throat. This allows for slightly higher velocities.

My idea is also to "foul" my bores with moly instead of the normal guilded copper jacketing of most bullets as protection. Still, I have heard both pro and con of the utility of this practice.

It may be my placebo effect, but those beautiful silver-blue bullets sure are pretty!! Does any one on this site use moly coating and what do you think??
