2nd time to load brass. neck sized will not chamber in same rifle. measurements seem to be same length. 22-250 what did I do wrong ? thanks

Neck size empty brass, don't seat a bullet. Will the brass chamber? If not, possible case stretch, or may need to set back the shoulder. Repeat with a full sized brass case. What happens? 22.250 does have a pretty sharp shoulder.
Peter.

I'll bet the shoulder has moved forward.

Did you use a Full Size Die but partial size?

How much of the neck did you resize? I seldom resize more than ½ the neck. If you try to shrink the entire neck, you may have impinged on the shoulder and created a doughnut at or just behind it.

Make and model rifle?

Or when you seated the bullet you changed the neck in some dimension.

If the cases were fired in a different rifle they may not chamber unless full length sized.

thanks for the responses. to answer some questions. rifle is kimber 84m ,used lee neck sizer die , cases used in same rifle. thanks again.

Did you check the length of the cases?

You may have altered the shoulder either while resizing or seating the bullet. I managed to do this on some 300RUM one time which also has a sharp shoulder when seating the bullets. The seater was set down too far and was crimping the bullets where there was no cannelure. The result is that the shoulder was bulged out enough that the loaded rounds would not chamber even though you could not see a difference. Could be your sizer is doing that also if you have that set a little too low.

yep pushes out the body shoulder junction just a hair... too much.

I have a 308 round in the shop I keep on hand to remind me to check stuff.
I could fix it and shoot it easy enough but it's a nice visual reminder that not always do things go as planned.
especially when your trying to get that round in the chamber while a pretty decent buck is standing 20' away from you [and the truck] calmly drinking water.
only one in the whole 50 count box like that and I just had to pick it out.

This is a problem that happens all the time and its not the case shoulder. The belted case sometimes expands excessively just above the belt and sometimes a special die is needed to size the case above the belt.

Color the case with a black felt tip marker and see where the case is rubbing/binding in the chamber.

Chambers and dies can vary in size and sometimes the cases are made at minimum distentions. Meaning a skinny case and a fat chamber can cause problems.

This has to do with the design of the case and chamber diameter.

Oh God! Will this myth never die? Besides, the guy is having difficulty with a .22-250, not a belted round.

The OP is dealing with a 22-250, it's not belted.

Sorry, wrong forum and alzheimer's. I thought I answered this belted question but did not post my answer in another forum.

"BUT" the black felt tip marker will still tell the OP where the case is binding.

And the same thing applies, below are two British cases fired in my Enfield rifle. The Prvi case is thicker in the base web area. And the HXP case is smaller in diameter and thinner in the base web area.

And the bulged area in the base of the HXP case will rub and bind if the case body is not sized.

And the same thing can happen with a belted case and is not a myth.

I fired 2 factory ammo and the fired brass chambered easily. I must have changed the shoulder in resizing or seating the bullet. as black tail suggested. will look closer when I pull the bullets. thanks for the information.

Glad you figured it out;no point in another old fart putting in his opinion.Everything that was said was I would have said,I.E. brass length. \etc. I have in the past had problems with AI brass but that is to be expected.Different chambers,different tolerances.The one truth in this is always use the same brass in that rifle.It's only my opinion but it's very true.

With regard to belted magnum cases I am not sure it is a myth. It was reported in depth in Precision Shooting magazine, and I do own one of those dies which I use for my 300 WM, 7mm RM, and 375 H&H reloading. I have a high regard for the reporting in Precision Shooting, but you probably regard it as "fake news".
I do agree that it is not clear what this has to do with the 22.250 neck sizing problem reported. With regular full sizing dies it is important to have the die seat firmly against the shell holder however.

Peter, I don't think you are considering the relationship of the sizing die to the chamber of an individual rifle.

Doing as you say could result in creating excessive headspace in the resized rounds. Conversely, some FL dies will not size the round adequately unless some thickness is removed from the shellholder.

Besides, when the brand of shellholder and the brand of die are different, there can be a significant difference in how the brass is sized compared to using some other combination of die and shellholder.

Even when the shellholder and die are of the same make, adjusting the die so that it is hard against the shellholder may result in excessively resizing a case for a particular chamber.

If you are using a neck sizing die, you have got it screwed down too much. This is affecting your shoulder.

Solution No1 - just screw the die back 2 or 3 turns and check measurements and if the case chambers easily.

Solution No 2 - do partial full length sizing and use this tool to make every round exactly the same size - EVERY TIME - for ever!

Look at this and other videos - https://www.youtube.com/watch?v=g4HsgB6u2sI

I have been using this tool for about 10 years and it has solved many of my reloading problems and errors.

Unless you are a bench rest / target shooter, I believe that partial full length sizing & using this tool produces the best, most accurate and most consistent ammo.

I also shoot a Kimber Montan in 7mm08 and it shoots very accurately with ammo made using this tool - even out to 400 meters!

The tool is so useful when you change bullets - you can get the ogive clearance from the lands exactly the same for all your bullets, if that is what you want.

Yup!

I've been there, done that and bought the t-shirt. That's why I normally adjust my neck sizing die to size only about half the length of the neck.

Keep this simple, you didn't run them deep enough into the die, I suggest you blacken the neck with a match so you can tell how much of the neck you are resizing and go from there..You may even need to full length resize depending on your chamber..In hunting loads I always full length resize, target loads only get neck sized and still Ive seen little difference in how long cases last and accuracy. a good chamber is the secret to lasting brass.

thanks for the responses. have pulled bullets and saved powder. plan now to full length size brass and load them.
