Ran into a problem casting Accurate 401-165 4x Alum. this week and time before that. Mold is really hard to open, plate swings easy, Lee handles work fine. Everything OK when cold. Cleaned this time real well, smoked heavily. Bullets are round, smaller than last time, no base flash, look really good. No problems in the probably 10 times I've cast with it previous. I may try scraping hardened lube from the pins. A/C ECO oil is a bear to remove, sticky? Bullets drop out by a tap on handle. Used a mallet to open plate so alloy should have cooled enough.
