Robgunbuilder.600 Bullet mold pictures
I really like this caliber. However, bullets and brass are hard to come by. I've been amusing myself for the last two days building a mold for a 900 gr bullet to be cast from pure Linotype. It's been an informative project and I just finished it and thought you all might like to see it before it gets carbonized. The first picture is of the CHERRY I made from water hardening 5/8 drill rod. I used this to make the mold. I only put three flutes on it and that was a major mistake. I now know that these things must have six flutes to cut properly. It worked in the end and at least didn't warp too much when I heat treated it. The rest of the mold was done in 6061 aluminum stock and if I had thought about it properly, I could easily have made a double cavity mold. Anyway it was fun and interesting.-Rob

<BMG>Way cool Rob,
The .622" (I can only assume) mold looks great. You are a wonder in the machine shop. Good luck on your Safari to the Dark Continent.

Paul HRob,
Would you consider making these available for the "600 club"? If so, and rough estimate on cost for a 1 or 2 cavity? The NEI .622" 900 gr has too small of a meplat for my tastes, but your prototype looks spot on.
Have you contactacted Hornbear about 600 RGB brass?
