The bras that isn't going in the gauge looks to be Federal, so it's probably boxer.
Yes, somehow you are supposed to know this in advance.With the Lee dies, it's the opposite, you run the die down until it touches the shell holder then turn it down a 1/8th or 1/4 turn. But the pin only needs to protrude 1/16th or so from the bottom of the case. If it pops up, that means it's too far down, and it's a safety feature. That's why it's so hard to reach the bottom of the sizing stroke.
I was wondering about this as well. On my single stage Lee press, if I fail to lube cases or don't lube the length of the case, I immediately begin getting resistance when moving the ram handle. When I continue by forcing it, I'll end up with a stuck case 9 times out of 10. The tenth one usually results in a crushed shoulder. Both of which are hard on the equipment and fatal for the brass.Maybe I missed it, but I haven't seen any mention of lubing the cases before trying to size them. Is that a step you've been taking before sizing? Be careful to not "over lube", but that could be causing the problems you're having. Brass is very prone to sticking in resizing dies without lube.
The expander should be used most times, keeps the neck from possibly getting damaged/dented when you resize. But raise it about 1/16th of an inch above where the pin ends up after you finished the stroke last time. I think you are hitting the bottom of the case with the expander, which is why it gets so hard to finish the stroke. The imperial wax is fine, great actually, so that should not be an issue.No. There are no berdan primers. And I am not pushing out primers. These have all been deprimed with a universal depriming die and cleaned prior to sizing.
When I get back to this I will try sizing without the decapping pin. The only thing that could be pushing that pin up a little is either the form part of the pin going through the neck, or with the pin flush, its going so far though its getting into where the taper on the pin starts and pushing it up. Thinking about it the latter is probably what's happening since is moves up a little and then stays. But I don't think that should cause the case to not fit a gauge.
I am using Imperial Sizing Die Wax. I have some Dillon Case lube that I will try. I have not had a stuck case.
I have parts of some trees down and the wife thinks that me cutting those up is more important than this. I know that's crazy, but you know how wives can be. It's supposed to rain today, if it does I will get back to this and try a couple of things.
This is the case. You may have worded the best so far lol.The expander should be used most times, keeps the neck from possibly getting damaged/dented when you resize.

This makes sense, and would also make sense that if the expander is getting that far into the case that the shoulder could get crushed. Sounds like you need to back your die off instead of tightening it down.I think you are hitting the bottom of the case with the expander, which is why it gets so hard to finish the stroke.
No. I don't think the shoulder is crushed at all. That's not how the die works. That rod needs to come up just a hair and the upstroke won't be near as hard. He's done said that he's tightened that nut about as tight as he could, which is not correct. That's a built in feature to help keep it from breaking the decap pin. That's why is keeps pushing up. It's designed that way.This makes sense, and would also make sense that if the expander is getting that far into the case that the shoulder could get crushed.

Ok, not sure if it's how you are describing it, or my understanding of it but here is how you should do it.Okay here is what I found….
I removed the pin.
Marked the press linkage so I could kinda tell if it was going all the way down.
Sat the die down 1/3 of a turn.
Reran a case that had die wax on it.
Still hard to press, press was all the way down, case still sticks up about .050 out of the gauge.
Turned the die in to about 3/4 turn. Not much change. The press was not going all the way. But how could it? It was hitting the Case holder.
Put the pin back in, backed die off to 1/3, made sure it was not hitting the case, switched from Imperial Die Wax to Dillon Case Lube. Acted like a different press. With the Dillon Lube it didn't take a quarter of the pressure to bottom out.
I can pop it up and down about 10 times and get a little deeper in the gauge, but still not flush. Maybe .010 to .020 high. The cases that are .010 to .020 high will chamber in my bolt gun, anymore and they won't without forcing.
So my assumptions are…
Either the gauge is bad, or the sizing die is bad. I can put factory loaded ammo in the gauge and its flush. So I don't think it's the gauge.
I can flip a case around and it will go 3/8 to 1/2" in the gage. I can run calipers around my case on the rim and the base above the rim. They are the same. So I don't suspect bulging or damage from the AR-10.
I believe that unless something is wrong with the press, and I don't know what that could be, the sizing die is bad. I think the shoulder is at or near max depth and can't go any deeper.
Does that sound logical?
That's my guess.You could have a die that's at max tolerance and a gauge at minimum.
Yes. And when I crank the die down more in the holder all that happens is it still stops solid except the press handle is not all the way down.When you raise the ram, with case in the shell holder, does the shell holder bottom out on the die face on a full stroke?
And these cases don't chamber in either of your rifles either right? After sizing that is.Yes. And when I crank the die down more in the holder all that happens is it still stops solid except the press handle is not all the way down.
