As others, I suspect the die. Do you feel resistance in both stroke directions when sizing?

I had this with a Lee die for A CM . The ball expander is a couple thousand to big call for the proper size mic the ball . I am guessing this is the problem
About responding to answers to a post: For me, I look at my computer first thing in the morning, and often don't get another chance until the next morning. I don't keep mail on my phone, because it interrupts me too many times during the day.
But, I'm retired, and you guys that are working may have more time to respond to posts.

Die is marked wrong or bad specs from factory . Neck is being over expanded . Try new dies. Good luck im very curious about 6.5 prc . Dont own one yet .

Wont be the first time Hornady screwed up a die. I never buy them.
I would say it's either a missed marked die or expander ball is wrong. I don't know if it's a bushing die or not. Mik the expander ball to start with, and check the sizing die stamp.
Well it is Christmas .

Pull the dies apart and then very carefully measure everything, that would be step #1 from an engineering perspective. Everything else's conjecture and guess work.

There is that I guess.
Both my thoughts....betting on wrong expander came with the die....easy enough to measure it..

My $.02. So I have started reloading since 1/2024 and only in the last month and a half have I loaded for my 6.5prc. I'm using a Forster FL bushing die with the .292 bushing. My brass is also Norma, but is once fired factory Golden Target ammo. My 1st reloads were ladder loads with H1000 and H4831sc behind 140gr Accubonds. Except for one cartridge that I could not close the bolt on and after remeasuring, I realized it was missed on resizing, I had no issues with lack of neck tension. But, on my second reload to test a specific charge of H1000 and H4831sc I liked, I encountered 3 or 4 rounds out of the 20 total that my neck tension just wasn't there. I was baffled. I even removed the primer rod from the die and resized those rounds again. I still did not have what I thought was adequate tension as I could spin the bullets some with my fingers. I then took another 20 once fired Norma cartridges and loaded a 10 ladder of Grand with 143 ELDX, and a 10 shot ladder with N560 and Berger 156gr Elite Hunters. Those had good neck tension. So I'm wondering if twice fired Norma with a .292 bushing isn't enough tension and I should go one size smaller to a .290 bushing. Since I'm loading for a hunting rund, I don't want to worry about a bullet that is just barely snug and have it shift in the cartridge or worse, come out and dump powder in my action or anywhere else. I just got home from my farm where I was hunting and load testing and haven't had time to fully digest all my data. What is y'all's opinion on the Norma neck tension issue I experienced and how it is similar to the OP's situation?
A few things you need. Calipers to check your inside and outside dimensions of the neck. A Vernier Ball Micrometer to check thickness of neck. For the Calipers you need comparators to check your case length to the shoulder, and while at it, comparators to measure your ogive on your bullets. The hole or pit.
Now you need to measure the O.D of the neck, and bullet. The I.D. of the neck. Do this before and after resizing your cases. Use the comparators before and after sizing your cases. Besure and write these figures down somewhere to compare the difference. You will know just how much your are bumping the shoulder back and the neck size before and after sizing.
Measure you bullet O.D. reduces that figure by whatever neck tension you want. Compare the diffecent between the I.D. of the neck to the bullet O.D. That will give you your neck tension or maybe none at all. I believe you said that you are using bushing dies. It could be you aren't sizing the neck down enough to hold the bullet, and or allowing the case to go into the chamber.
Now for more problems: I don't believe you are cutting your neck for thickness. So you'll need to have setup to use a mandrel to expand the inside of the neck to straigthen the neck out and set tension at the same time. So back to the tools or measuring devises that you need. If you have them that all the better, but you need to use them.
I think I have covered it. Knowing me I probable missed something.
