Help.... this is the first time that I am fearful and worried. It goes like this......... Dropped good bullits from lee mold, (#90329 ?) its a .311 gas checked bullit @ 170 gns. I am sizing them in a Star with a .312 die. Its to just smooth & lube and seat gc. The gc. is on but not really tight (good tug with fingernail). I wantn to work up a load for the Mosin. Loaded win brass w/13 gns Unique and seat bullit to crimp groove. This puts base & gc. below neck. Well a bullit stuck in seater die and pulled out of shell but left the gc, in the powder. Now im worried that all 30 rnds. will drop the gc's . Will this cause a bad chamber rise if the gc. makes it to the neck in mid detenation? WHAT say ye all????
