I am using a Lee #4 shell holder.
Plant.One - Thank you for that schematic. I measured a handful of sized and fired brass. I'm going to list some of my measurments below (I'm not the greatest with calipers and got some variation over multiple cases).
Cases are trimmed to 1.745/1.750
Right behind the shoulder - Sized .352/.353 Fired .355/.357
Case Web - Sized .373 Fired .374/.375
headspace with the Hornady Comparator- Sized 1.464/1.4665 Fired 1.465/1.467 These were essentially the same, the very slight difference I would attribute to slight primer cratering on the fired rounds. I was pretty confident that these measurments are correct, so it seems that my sizing die is not bumping the shoulders back at all. Is that correct?
I have the die set so that the shell holder touches the die when the ram is all the way up, so it sounds like there is nothing I can do other than grinding .010 off the shell holder.
AWS- I do not have my seating die set up to crimp at all. I haven't pulled these yet but the last time I pulled some 223 there was zero crimp marks on the bullet.
And again, this problem with the rounds getting stuck only seems to occur with my Winchester cases.
