I have not Clem, but it's an interesting idea. Do you do your own powder coating of the bullets for your lever actions? Do you think there may be advantages other than messy lube vs. powder coating thing? How about an accuracy comparison of lubed vs. powder coating in your .45 using Ed Mehlig's 350 or 460 grain bullets? It would also be interesting to shoot both types over a chronograph to see if average velocity changes. Heck, old guys like you have nothing better to do anyway.
