The Machinist man,has told you the facts ! There is, actually ,very little advantage to using moly,other than in a big bore gun. Besides,the moly craze,has almost completly passed by !
I have read about shooters,taking gun barrels and sawing them in half,length ways,to see what was up with the moly. The moly had built up and was layered with copper fouling.
Anyways, IMHO,to use it,once in a while,is like being half pregnant ?<img src=icon_smile_dead.gif border=0 align=middle>
