I would think that there is NO copper alloy that would wear out the steel rifling in a barrel. The thing to watch for is higher pressures, since the copper doesn't "give" as much as a lead cored bullet does. I think that is why some of the makers of solid bullets machine rings into the sides of the bullet... to give the displaced metal (from the rifling) someplace to go.

I've been giving this some thought as well.. I was thinking more along the lines of brass rod, however.
A screw machine would probably be the berries for this type of job.
