Ball swaging die

[Hdskip]

This is a project I made years ago. it is a swaging die for a .45 cal round ball. A pre cut slug was placed in the cavity then the die was closed as far as possible. The die was struck with a heavy soft faced mallet. A relief was around the ball cavity to allow some place for the flash to go. The ball was removed and pressed through a flash removal die. the process was somewhat labor intensive. It produced a beautiful ball.
Testing was done using cast balls vs. swaged balls. There was no noticeable difference in accuracy from my left handed flint lock Tennessee rifle. Both types of balls shot to same point of impact. After shooting all balls produced I felt that cast was the easier way to go.
The die was made from O-1 tool steel and hardened to about 56 Rc if my memory serves me right. The die also serves as a cutter to cut slugs to proper length by pivoting on one of the pins. It was a worth while experiment even though it is seldom used any more.

Looks like an arbor press could be employed to increase productivity. Cool project.

I tried the arbor press but the impact type extrusion seemed to work more efficiently. I never got an opportunity to try a hydraulic press which I think would have worked very well.

Would you make one for a .490 diameter round ball possibly? Please.

John,
I'm now retired and do not have access to the equipment to accomplish what you ask. I have a mill and a very small lathe and no access to heat treating and surface grinders. Could it be done? Yes but time and effort would make the cost prohibitive. Best I could do would be part with this one. but that would not solve your need for one for a .490 though.
Nevertheless if anyone has an interest in this one it could easily find it's way to a new home. I don't use it anymore and it truely is a nice piece of equipment. I don't mean to brag but it was done correctly.

Good evening
That was very interesting ! Nice work .
I do wonder what a "chunk gun" could do with a perfect RB ?? That would be a very good test platform to determine whether your work was indeed "worth the effort". I do not have a chunk gun and my only caliber .50 Green Mountain barrel has not been mounted for near 20 years. That flinter (a swap barrel) has the caliber .36 mounted which is my small game muzzle hunter.

The issue is that perfectly round ball is only in that state until it's deformed when you load it . And then it's deformed again from the opposite end when it's launched back out the barrel . Yes it's still a mostly round shape but it is not in the original perfect form .
