H&G 10 Cavity Mold Mod

[38ExtraSpecial]

So I have a few of these old moulds

Most of which were rode hard their whole lives. I have one gem that must have been a backup because it’s in OK condition compared to the others. I’ll keep that one original.

So I decided to mill one down a couple lube grooves and make about an 80 grain waductter from one of the ugly moulds.

Let me tell you it wasn’t worth it . Shave off 1/4” of steel and the mould still weighs a metric ton. Damn near through out my shoulder each time I filled the mould. The end result is serviceable but the mould is so beat that it’s not a really pretty bullet.

I guess I need to find a modern brass mould in a 75 or 112 grain wadcutter

I had some flashing on the bases but I didn’t really pick the nicest sprue plate. I have half a dozen spares to choose from and this one was on top of the pile. I think cleaning that up a bit could solve some issues.

Anywhere here’s a zoomed in pic of bullet taken under an LED bulb with lots of glare but you get the idea.

Very cool. Pics of the mold?

I’ll get some tomorrow. I left it in the shop after casting. It takes two men and a boy to carry it inside the house.

I should have taken a better picture of the sprue plate. It’s 1/2” thick or better.

There are thinner plates 1/4” or so but even those have a raised area all around the sprue to make the “trough” twice as deep.
