ywep, those pins will fall out!on a new lee, one fell out in about an hour casting. i just check them really often now, and peen them in if need be...also, i got in the habit of turning my molds over and checking to be sure the halves are closed well, i just tap it lightly with the sprue stick to nudge the halves together...for the price, you can put up with a few quirks, and those bullets shoot fine!
