I have several hundred resized and primed 22-250 cases that were fired in an old factory barrel and chamber. My new krieger 22-250 barrel and chamber is tighter! Is there any safety issues with resizing these primed cases using a Redding Full Length Type S Bushing die so that they will chamber ? I would remove the depriming pin and neck bushing and size until they chamber easily.

I can see nothing wrong with what you wish to do. The only time a primer will go off is if it is struck or subjected to some sort of impact. I see no impact in your procedure.
As a added note, some cases might not size down, depending on how much larger the old chamber was. But, it only takes a minute to run them through. Be careful you do not bump that shoulder back too much .........jackie

Safety 101 says don't do any of the things you're proposing. Start over with new brass that will eventually be fire formed in your new chamber. You can salvage the bullets, powder, and primers but I'd recommend discarding the brass unless you have retained the old factory barrel that you intend to use sometime in the future. That's the ONLY place I'd ever use that brass again.

You need to get a tool that you can measure the shoulder to base length. Then size a few [ 5 or so ] of the cases incrementally until the bolt closes with only a little drag [ remove the firing pin ]. Measure the shoulder to base length.
Go shoot one with a mild load and the bullet seated well out into the lands. Then measure the s to b length. If it is only .002 to .005 longer than the length from above then you should be good to go. Shoot the rest of the 5 or so and adjust the sizing die to bump them back about .002 and then see if the bolt closes easily [ FP out ]. If it does then you can size and fire the rest.
If bumping back the shoulder .002 on the fireformed cases does not allow the bolt to close easily then most likely the web of the case is too big. A small base die may take care of this or the brass may be too expanded to ever work correctly in the new chamber. A small base die may allow you to bump the shoulder back the correct amount and size the web enough to allow for easy bolt closing but you will probably have difficult extraction of the fired cases.
You have to weigh the cost of the small base die versus the cost of new brass , new brass being the better solution .
Skips Die Shims are very handy when doing this sort of incremental shoulder bumping.

Take one case and deprime it slowly. What will also be safe is to turn the shellholder around once you insert a case so nothing can blow back at you. Then size the case...color it with a black marker...keep repeating until the case will chamber and at the same time you should notice less scraping of the brass. After this...set the die and then size the rest of the primed cases. Do not use a spray lube because you don't want to get any inside the case and down on the primer.
