The pot is a good one, and keeps very constant temperature. The dies are Lyman 457658, and on the box it says this should make a 480 gr. bullet. The melt is comprised of range salvage plus 5lbs of pure lead from Rotometals. Over the course of casting 45 bullets, the weight of the bullets rose incrementally from 494 to 501. I weighted every 5th bullet in order to establish this.
Just like everybody else, I would like to make a big batch of bullets within one grain of each other. Anyone know what is happening here and how to control it?
Thanks
Ron
