Claims15
A method of supplying bullets for hand loaded ammunition, comprising:
- providing a kit for use by an individual reloader, said kit including a bullet core material comprising a polymer material and an instruction guide that includes instructions, the instructions comprising:
- selecting a quantity of said bullet core material;
- heating and melting said quantity of said bullet core material until said bullet core material exhibits flow qualities and to a homogenous state;
- and
- manually disposing said quantity of said bullet core material into one of a bullet jacket and a mold, the manually disposing including injecting the bullet core material,
- wherein the heating and the manual disposing is performed with a heatable pressurizer.
