Frosted Bullets Coming Out Of The Molds
Frosted bullets are generally a sign that the mold is too hot. Let the mold cool for minute or two with the blocks open and sprue plate open. You may also want to lower the temperature of the pot. Once you reach a spot where you are seeing wrinkled bullets, you have gone too far. Slightly adjust back to a hotter temperature and you should have achieved the prime temperature setting for your pot.
Frosted bullets cause no problem when shooting so it is not necessary to discard them back into the pot. In fact, frosted bullets tend to cause the Liquid Alox to adhere even better which is very desirable, especially for bullets meant to be shot at higher velocities.
