I have some Rem brass that has been shot twice and didn't grow. 30-06. First was factory load, second was 56.5 gr of IMR4350. I am knocking out the primer before measuring with a with Lee Collet die, but only taking out the primer not resizing the neck. Measuring with Hornady Headspace guage - 2.035" head to datum line. Did the brass not move or am I doing something wrong here with the die?
