I have never loaded with a single stage. I started with a Progressive. I recently acquired a Herters Single stage press and have the shell holder adapter from C & H. Here is my question: When using a RCBS collet puller I have to guide the .223 round into the collet. There is some wobble in the round when I am raising the ram. Is this normal? I am using the appropriate Lee Shellholder. It will slow things down a lot if I have to guide each round into dies by hand. Any input is appreciated.
