This particular slug/load shoots quite well!
I was lucky to find a guy who was selling this mold cheap at a time when I actually had money. NOE made the thing, mold is marked 314 SP 129 grain. I size to .311 when i gas check 'em.
With the a hard alloy i have, it doesn't lead any barrels, not even the gas tube in my SA vz-58, making it a great gas gun cast bullet. Yes, all are loaded on a single stage press, so I get to know them as individuals, too.
