Increasing mold diameter

If you need the mold diameter of your cast bullets to be increased just slightly, there is a way to accomplish this at no cost.

Apply some lube to the mold blocks face, away from the bullet cavity. Place a small piece of cigarette paper or writing paper to the lubed block.

When casting the bullet, the diameter of the bullet will be increased by the paper thickness. You can actually go up to about .010 before you begin to see lead flashing appear. While the bullet will be slightly out of round, this very minimum amount will not effect accuracy or the manner in which the bullet travels through the forcing cone and barrel of your gun.
