Case head expansion & ready to retire

[Unclenick]

One issue with repeated sizing in steps is that most cases don't resize fully on one stroke. So, for example, if you had on, as Paul described, that is just on the snug size, if you ran it back into the die at the same unadjusted setting, it would come down in size a little. Indeed, if you run it in and hold it for three to five seconds, you can get as much as a couple thousandths of shortening. So, when you go through the adjustments as Paul described, be aware that a case that hasn't yet had any resizing done to it may come out slightly bigger than the initial test case, and you may find you need one more tweak for them.

Here is an old file I made that you can print out, cut out, and apply to the die or the press to see how far you are adjusting the die.

totaldla: with a 223 bolt gun (of course i neck size for that) it is easy to get 15 cycles and 20 is not out of the question, and i do load close to max. for that gun.
