.22-250 cases difficult to chamber....

The good news is You have just proven without a doubt to yourself that no two pieces of brass have the exact same fatigue rate before they need annealing or a specific amount of sizing in order to fit a specific chamber.. My advice falls into the category of your last sentence. Don't fight it lol.
Good luck.

OTOH it could well stem from a load with inconsistent shot-to-shot pressures. OP did you happen to clock the loads tested?

I would not be surprised if you are trying to neck size with a FL die. When the die body begins squeezing in the case body the shoulder has no where to go except forward. During the first year of my reloading life I also ran into this phenomenon. With a properly set FL die you will not have to deal with this issue again.
With moderate loads you can often used a purpose designed neck die without chambering issues. A real neck die does not contact the case body so the shoulder does not get pushed forward.

NO, it gets pushed forward with pressure. Where this thing about accuracy and brass lasting with neck sizing came from along time ago. Neither is true. With annealing and full length sizing cases can last 50 loadings or more. Accuracy is another issue where myths say the case needs to fit the chamber tight. I have seen some of the best 1000 yard groups shot with brand new brass that is very loose in the chamber. Even when the shoulder is being pushed forward a big amount. I believe it all started with the die companies wanting to sell another die. Matt
I did chrony them
I use a neck sizing die as I said.

>>>>>good point.. I have been loading for 45 years. that's why i'm on here. new ideas!!!!
First - I did not say a thing about neck sizing and accuracy.
I think you are missing part of the picture.
Second - The shoulder gets pushed forward by a FL die when it is set to use as a NECK die. Everyone but you seems to know this.
I have done it many times. I can prove it anytime. Take your datum bump tool and a conventional FL die and try it.
Just set the die about 0.060 off of the shell holder and size a case with no expander. Measure the shoulder location. Turn the die down about 30 degrees and size again. Before you hit the shoulder of the case with the shoulder of the die the case shoulder will start moving forward.
When you get through then explain how the shoulder gets blown forward enough to make chambering hard because I have never seen it. Hard chambering always results from something wrong with the rifle or poor sizing technique- meaning you squeezed the case body enough to move the shoulder forward.
A neck bushing die is often used because it requires NO lube. This may be a good reason to use a neck bushing die if accuracy is otherwise acceptable.
You can quote myths all you want but many people get excellent accuracy in spite of your claims.

What you said was you neck size only.
You did not say what kind of die was used.
There are people that try to neck size with a FL die and they wind up wondering why their rounds are hard to chamber. This is more likely with a case that has little body taper and a short neck like a .243.

I have brass shot once/twice. I neck size only. about 30% are very difficult to chamber. rest are typical of neck sized cases in how they chamber.
They are trimmed to proper length. chamfered/debured .
Other than needing FL sized/shoulder bumped, any thought?<<<<

There is just no reason to neck size. You should be full length sizing your cases every time. You will see improved accuracy and reliability. Your cases will last very long if you dont over do it.
I am not disputing any of that but some people still use neck bushing dies because they do not require lube or a 7/8-14 press at the range.
Re-read your own post.
You did not say you were using a NECK DIE.
You said you were neck sizing. There are at least 4 different die types that can be used to size a case neck and you did not specify which one.

ireload2 is correct, you did not specify what die you are using in your original post. Specifically, what die are you using? dedogs
cases won't fit in chamber

And ... ? What was the ES, and could there be a correlation with the case growth variation?
