I always preheat the boolits before tumble lubing them, I use a heat gun.
I have never used LLA straight, I have only used 45-45-10 (2 coats, before and after sizing) ...until recently, when I started using applying 45-45-10 before sizing, then BLL after sizing.
With my method, the boolits are dry to the touch when the boolits cool to room temp (10 minutes or so), But, I still let them sit for at least an hour, so they are thoroughly dry and ready for the handling that's involved for reloading.
