I have ONE cartridge. I was wondering if I take it apart, can I somehow make a mold to make more bullets ?
Not to be a smart a$$, but I edited your post to correct terminology.
Now to ask a question? How heavy is the bullet? The reason I ask is lee already makes a .500 440 grain gas checked bullet for the 500 S&W magnum. It's a WFN or Wide Flat Nose configuration. Another ?. What ype of firearm is your ammo fired in? We need more info for a specific answer.
