I need to make some for this old .338 mould. Any .338 bullet is expensive so it will be a real treat to be able to make my own hunting .338 projectiles. It is a HP type mould with a hole for a pin to protrude. You can make different lengths or a stubby for no HP.
I can make pins from Aluminum, Copper, Brass, or steel. Each has it's own qualities of heat transfer and expansion. I'll probably make wood handles for them too. You pull the pin out after pouring a bullet around them, then drop the made slug.
Most old moulds used steel and I have made them from common nails before. Just a slight taper and polish on them to help slide out of the hot lead.
The pin is only 0.015" in diameter, but I can make it up to about 0.665" long penetrating the nose to about the driving band.

I figured it would be real clean.

that is what I would do. A 338 bullet doesn't need to be

At lower velocities it can become a Partition
