I used a Lyman 457193 mold. I took 29 lbs of pure lead and added one lb of pure tin that I got from a lab ( not solder). I was expecting to get about 420 gr bullets, instead I got 405 to 406.7 for the 45 I cast. They filled out nicely and have a diameter or 459 to 460 pretty consistently. Got 'em in a pan of Gatefeo's best lube now. Now to cut some over the powder wads and hand prime some new Starline. One step at a time.
