One of my current projects is to cast and load for the 8x57JR, with .318 groove diameter barrel, 1 in 12" twist. It seems that any one of the following molds could work: 323481, 321297, 323470. Wheel weight metal would be used. I thought to purchase a .320 Lyman sizing die, if available, which would put the boolit .002 over groove diameter as the bore has been slugged and found to be .318. Here is where the questions start. Since current 8x57 Mauser sizing dies are set up to size and crimp for .323 bullets, I assume they won't work for the .318 application. If not are there die sets specifically for the 8x57JR? If so, I need to find one of those sets. Next comes brass and shellholder. I would like to find brass with the 8x57 JR headstamp which would seem to be more compatible with .318 bullets or boolits. I also need to find which shellholder fits this case head. Lastly can someone point me to a dimentioned drawing of an 8x57JR? I plan to post in the WTB section once it is determined which mold, dies, sizer, shellholder, and brass to buy. If anyone has any of this they can let go I'd appreciate a PM on it. So what does board membership say about this project? Thanks in advance for your valuable input.
