hello. I am in the process of decapping .40 cal brass and I seem to be having trouble. I have to cycle the press twice on 90% of the cases in order to get the old primer to pop out. I am new to this and perhaps I dont have the resizer seated propperly. I have adjusted it three times according to the nstructions and I am afraid that if i get it to tight, I will snap the pin. I am using a single stage RCBS. Any thoughts will be appreciated.
