It is rather embarrassing admitting this, but so what. How is one to learn? This kind of chaps me as it is error number 300,000,000… For the purpose of this example I will use the 22-250 caliber. With Redding Type S Full Length Competition Die, I was decapping AND neck sizing on the same pull of the handle…at least I thought I was. The decapping plunger is .222” diameter and I had a .243” neck size bushing installed in the die. I have obviously come out of my coma and can see now that I thought I was varying neck size with different bushings in the past but most certainly I was sizing one dimension on the downstroke and when the plunger/decapping holder exited the case it resized the ID back to approximately (considering spring back) about .222”. So just to confirm my understanding of my error, I must decap and then neck size, in that order, correct? If my understanding is realigned, I guess I better start all over in load development as I was never varying any neck tension. Thanks!
