I’m loading 45 acp on my Dillon 650 with large pistol primers and things where great, then suddenly I am getting 20 percent proud primers. I have been through the manual, my shell plate is stable when I push the handle ahead the punch is high enough to seat a primer properly without a load on it. When I’m loading brass that does not seat easily they are proud,the proud primers have a dent from the punch, any ideas are appreciated. I’ve loaded a bunch of this, I can’t figure out what has changed,Dillon guy says maybe a cracked crank. I’ve laid on it and can’t see a crack.
