I've been having immense trouble as ALL the web sites I've looked at ONLY offer pistol molds!!!! What a crock! I need a web site that does rifle molds other than the mainstream; saeco,lyman,RCBs,LEE etc.
I made my own from a Lee C312-185-1R. It takes some work to lap it out.
Make a casting, drill a hole in the base. Insert a 3" drywall screw in the hole, chuck it in a cordless drill then close the mold around it with some 220, then 320 and finally 600 grit lapping compound. Spin a minute or so in each direction in each cavity. Clean the mold and make another casting. Check size, repeat if necessary with new size boolit.
It took me three sessions to get a boolit to drop out big enough to size down to .316.
NOTE: try not to get much compound on the gas check shank, or you'll have trouble getting the check on.
