TRY ONE SHOT CASE LUBE AND KEEP IT OFF THE SHOULDER AND CHECK THE VENT HOLE IN THE SIZING DIE AND MAKE SURE IT IS NOT PLUGED WITH LUBE.gun)
Not to hijack but I always use the old sticky rcbs lube , What is the one shot stuff that your talking about and how does it work?
Just my personal experience, but with One Shot I get a dented shoulder about every 8 cases through the die unless I pull the die before then and clean it. If I use less One Shot than that used, I'll start to have cases stick. So, I went back to Imperial. With Imperial, the cases size easier and I can run 40 cases+ through the die without denting any shoulders. Due to the fact that I have to clean the die every few cases, One Shot does not save me any time. Just my experience. Take it or leave it.
