Pan Lubing Gas Checks

[joecool911]

I watched the videos on pan lubing. Looks simple enough. None of them were with gas check bullets though. Would you size and install the gas check prior to pan lubing? Otherwise the gas check area would fill up with lube and require removal???

Yes, install gas check and size boolit (in Lee sizer), then pan lube. I noticed that little bubbles would come out of the base of the boolit (with gas check) when it was heated in the pan with lube. Must have been the trapped air expanding do to heat and coming out.
