Very interesting and it is pretty neat. Forgive my lack of knowledge on this subject, maybe you could explain why you would copper plate the bullets. I do know that you can't or really shouldn't shoot lead thru a gun with polygonal riffling, as it can cause damage to the barrel. And the manufacturers will not honor a warranty if you shoot lead in one, kahr and glock to name 2.
Plating is like almost putting a jacket on . Plating stops most all the lead fouling, eliminates the need for nasty sticky, smokey bullet lube. And you can push platted bullets almost as fast as jacketed.
Ok ....that makes sense. It would seem unlikely though that the coating being so thin can do that. But I guess when you consider the short distance and speed it travels thru the barrel it becomes a non issue.
Yeah I think a progressive press would be nice. But I'm not shooting hundreds of rounds at a time anymore.
It might be a little anal, but I like inspecting the cases at every step. Making sure there's nothing to break the decapping pin, the flash hole is open and ready, and there's powder in it before I seat the bullet. Then I inspect the finished round.
