Got my new Lyman 457125 and 457132 molds in today from BACO. I used hot soapy water and a brush to clean them, dried then and then wiped the cavities out really well with alcohol. Let that dry and began to heat up 10 lbs of 30-1 in my Big Dipper pot. Once everything was up to temp I began casting. The 457125's came out great. They have crisp grease grooves, nice flat bases and are consistently weighing 501 to 503 gr. The diameter is a consistent .457. The 457132 is a whole different case. It weighs from 507 to 511 (I weighed 20-25 ) and the diameter is pretty consistent at 454. Wonder what I did wrong? The 457132 should pour at about .457 and weigh 535. Could I have smoked the cavity too much? I think I did both molds exactly the same. Also, the 457132 was missing the two screws that hold it on to the handles. Had to borrow them from another mold. Not a great start casting a bullet that shot so well in my rifle.
