The 30 CAL Check Maker punch’s a check the will fit nicely on a .282 shank.
You can use .014 aluminum or copper flashing that is not hardened.
The punch threads into the top with a 7/8-14 thread, the die slides into the ram in place of the shell holder.
If you mold cast a different size please fill out the form and let me know what the shank diameter and height is and I will make it to fit.
