Re: New Ohio Member needs advice on neck tension
Is your case length correct? That is the only thing I can think of that might make the crimp. If it is seating it deep enough, the edge of your die could make contact with the case.
I anneal my 30-06 after 7 firings, I would think after 2 your cases would still be ready to go.
I would make sure I had my resizing die set correctly then give it another go; measure the inside diameter of the case necks for uniformity after resizing.
I am new to reloading, (I don't know how experienced you are,) but I was not resizing my necks correctly at first. Recheck your directions and make sure everything is exactly as stated.
