Startup equipment for powdercoat is cheaper, supplies are cheaper, last I checked, and powder coat can be pushed harder, and doesn't smoke as much. Once you add in the cost of electricity the benefit probably goes back to wax, but for commercial sales, not having to set limits on FPS, not having to offer 1/1000 increments on sizing and not confusing new customers with alloy/hardness, and for that matter having to actually alloy lead, and test it, will more than make up for the additional cost. I always just shot cast bullets without lube, and limited velocity to around 900 and did fine.
