OK, I took my quenched .310 bulets and ran them thru a .311 sizing die to lube and seat the Hornady GCs. Now I notice the GCs are loose. They spin on the base of the bullet. They seem to be staying on, but as I say are spinning. What now ?
I thought maybe putting my .310 die back in and adjusting the depth screw to just run them in only far enough to tighten the crimp of the GC and not size (and therefore soften) the bullet itself
