I run the Lees pretty hot, but cool them off by resting them on a water soaked cotton sock between casts. (Tip from one of Lee's manuals,IIRC)
Periodic cooling in that manner keeps me just at the fringe of frosty bullets, where I get nice fill out, and allows me to cast rather quickly.
I'm doing my casting sessions lately as well.
Did 240gr .430 LSWC-GCs and .309 FP-GCs last night, and new wheelweight smelting/ingot making over the weekend.
Next up are 200gr .430 RNFPs. Handgun and rifle casting with w/w alloy is so much easier than pure lead casting of huge shotgun slugs, buckshot, and muzzleloader minies and ball.
