I believe it is used to compress black powder in cartridges. I also think it might be missing the stem. This is what I found at Midway USA. I hope this helps someone.
- Compression dies are used to compress the black powder in the cartridge case to a consistent depth.
- The die body has standard 7/8 x 14 thread to fit into any single stage reloading press.
- The stem threads into the center of the die body and is secured with a nut on the threads that bears against the top of the die body. Stem threads are not calibrated or otherwise marked.
- Compression die with stem is the body with one stem that is caliber specific.
- The stem (only) can then be purchased in additional calibers or gauges for use in the die body.
- If stem setting in body must be maintained exactly, then multiple die bodies would be needed, one for each stem.
- Shotgun stems are not sold with a die body and must be purchased as an accessory to a body with stem.
- Montana Precision recommends that a compression die be used for black powder cartridge reloading and that a bullet seater should not be used because it can deform the bullet. Instead, the bullet should be seated into the cartridge with finger pressure only.
