I was not sure how much you could size a bullet down in a Lee push through sizer die. Well I wanted to find out just because I can and I wanted to see what would happen in the end. Powder coated Lee 358-158gr bullet. Wheel weight lead. Before sizing . Diameter...weight.....length.. .359"........ 161.5 gr.....660". After sizing. No lube 311"...........114.6 gr.....565". After sizing with Lube. .311"...........121.9 gr......601". Softer lead with lube. .311"...........123.0 gr.......610". Yea I took a cast lead 357 mag bullet and sized it down to fit a .308 in 1 step. Yea do not try this. Maybe do it in steps. It made a ring of lead around the push through sizer stem. But it did work. I will size again to .309" after powder coating them.. got to remove some sizing die wax first. I get a straight wall no lube groves. Picture of course What good is this experiment. Lets say you have a dead mold that tosses crappy bullets or the bullet is just not one you use because accuracy is bad. You could drill it with a regular drill bit and make it a size you can use and then size it down. Looks like you can in fact size it down nearly .050".
