[QUOTE="Trickymissfit, post: 748148, member: 25383"] if you use a neck only die (and I do a lot of the time) you will eventually have to set the shoulder back. There's no way out of it. You can buy a bump die and push the shoulder back three or four thousandths and start all over again. But if you have a full length die your already doing this (if you have it setup right). Now the part about neck sizing only really partains to a custom chamber as there is little benifit gained from neck sizing a factory chamber. Many of us still do this in factory chambers to reduce bullet runout by turning necks, but other than that there is very little to be gained. By chance that you were lucky enough to get a chamber cut on the minimum spec, then there is something to be gained of course. Now if you happen to be shooting belted cases you will eventually get to the point where the area just above the belt will get tight. A standard full length die won't get you there most of the time (if any at all will). Then you need a die to also resize that part of the case. I see that with my .450 and my .270 mag after four or five high pressure loads. They'll still chamber, but they are a little tight. I agree with you about the barrel/bridge expansion and the brass meeting it's yield strength and beyond. I know of no one that goes thru life entirely with a neck die, but also know lots and lots of folks that neck size a lot of the time. gary [/QUOTE]
