My two moulds from the Group Buy came today. I cleaned the moulds & sprue plates with alcohol & nylon brush. From there to hot soapy water. Once clean & dry I mounted the handles & placed them on the Master Pot to warm. I used straight wheelweight alloy at 750 degrees.
I cast for 15 minutes with poor results. Raised the temp to 800 & still to many rejects. At 850 good bullets began to fall from the moulds. You might say that's a little warm but for the new moulds & this batch of alloy, that's what it took. Maybe next time I can run cooler.
Moulds came well packed:

Now the specs:
Bullets measure exactly as said, .432

And sure enough 3 random bullets weighed exactly 258 grains, yes all three:

Did I say exactly?
