I was loading some 300blk, Forster full length sizing die, with some random brass. I was using some Dillon case lube, all the brass prior to this one felt fine ran this case up and went to pull back and knew immediately I was screwed. I’m not sure what caused it, but I was able able to get it out, only issue is bent the primer pin nut.
As for my setup, I’m using a Dillon 550. Manually measuring my powder charge with a funnel over the powder through die. Measuring charge before raising the ram, insert brass raise ram, pour powder charge into funnel, lower ram rotate and repeat. Only thing I can figure is the few seconds while pouring the powder is letting the brass stick. It’s not uncommon to get some resistance initially while while lowering the ram, but nothing like this.
