So I'll go a completely different direction because that's what I do. Go up on the ram and give the case a ten count while in compression. See if you get a better result.

I may have to try your method 11MikeMike.
Even after cranking the sizing die down they still don't chamber in the T3.

When reloading military brass, do you full length size, or small base size? The attached pic is full length sized and trimmed to length, but the brass does not fit my chamber gauge.
It looks like either the brass was not trimmed to minimum length or the shoulder needs to be bumped back a bit more--or both.
I have never had this problem resizing military brass and I have done thousands. Me-thinks you need to change something.
It is not that you are lucky, but fortunate enough to not be unlucky.
The vast majority of folks do not have an issue of resizing bottle neck cases with standard sizing dies.
At least in my case, I've had chambering issues where I had two or more semi-auto rifles chambered for the same cartridge. A different standard sizing die did fix the problem but I've decided to purchase small base sizing dies, when available, when I add a new semi-auto rifle with a "new top me" cartridge.
On another subject, I've sworn off once fired military cases unless I'm sure of what they were fired in,. I got a bunch of 308 Win cases that had been fired in a machine gun. A large percentage of them had case head separation on the first reload.

Trim to length is good, double checked several times. I'm thinking it's the shoulder, I have tightened the sizing die down a lot more than normal. I really don't like putting that much pressure on my press.

You may also consider taking a bit off the top of your shell holder! 600 grit wet sand on a flat surface. Good luck.

My neighbor had problems sizing some 7.62 brass. I had sent him a link on what to get and he ended up buy the cheaper MG fired brass instead. I was able to size them in my setup but for him to do it I annealed the whole lot. Then he was able to size them. When he went to trim it was very obvious which ones were MG brass since it was 0.015-0.025" longer. The MG brass had case separation on the first firing. So he ended up scrapping all the MG brass. He was using a old RCBS Jr press, which explained why it was taking a lot of force. My Big Boss II press did not have any problems with them

Most 223 dies are small base dimensions anyway. I wouldnt worry about it unless it proved to be a problem.

It's the shoulder not setting back with one pass through the sizing die. By running them through 3-4 times, turning a quarter turn in between, they now fit my gauge and the chamber.

Thank you for the information. I don't usually reload mil. brass, I think I will be able to process enough for the time being to get me by. That is good info, I didn't know that was an option.
