Using the Corbin JMK-P-H Jacket Maker Kit, you can convert copper pennies into rather good inch-long 308 bullet jackets, assuming you use either the CHP-1 Hydro Press or the CSP-2 Mega Mite press with long handle option. The JMK-P-H requires copper or 95/5 alloy pennies, not the post-1962 zinc pennies which have a copper plate or wash. Those will not withstand the heat treatment, nor the drawing operation, and will either turn into a silver puddle when you try to anneal them, or will crumble and crack if you try to draw them. |
Here are the steps to turn a copper penny into a 30 caliber bullet jacket (which can be redrawn to make smaller jackets such as 284, 277, 264, and 257 caliber -- smaller sizes may or may not be satisfactory unless annealed again to restore the drawing capability)...
