[QUOTE="bigedp51, post: 1314518, member: 28965"] [LEFT]I was sizing 9mm pistol cases last night with a carbide sizing die. The die was screwed down until it touched the shell holder and then backed off a smidgen. With the naked eye I could see the air gap increase between the die and shell holder. And I could also see the die ever so slightly move, and this was just the case pushing upward on the "dry" carbide die. I can't tell you how many times I have read in forums of people using a progressive press getting varying case headspace lengths when full length sizing. And this is due to the press design and slop in the sizing operation. And Glen Zediker in his latest book tells you the die shouldn't touch the shell holder because it strains the press. All I can say is my 44 year old Rockchucker press likes hard contact with the shell holder with press cam over for uniform shoulder location. Maybe some of you have new presses made of super cast iron that never flexes when push comes to shove. :D And if the OP had a Hornady cartridge case headspace gauge we wouldn't be reading his posting here.
