Found a few of these in my Dad's stuff, but don't remember finding a mold in his stuff. Quite possibly he traded it off, he doesn't seem to remember much about it.
Anyone have any experience with one? Seems a rather unorthodox design. I sized these to .311 and checked them today, gonna try them in .308. My latest Lyman manual doesn't have any data for it. Just wondered if anybody had any experience with it and if it might be worth chasing down a mold for (I have a lot of .30 caliber molds now). Guess I'll see how it shoots in the next few days.
