22-250 AI, tight brass

[dunraven]

had a new tube put on a remington 700 in 22-250 AI, and ever since my brass is so tight in the chamber that it's difficult to close the bolt. am using redding s type dyes( 3-die set which includes a full body die, and a neck die). I have the neck die set so it 'cams over' slightly. I can push the brass all the way into the body die. Still the brass is tight. Is it the shoulder that is not being touched? Was the chamber just very tight to begin with? what's the answer, please?

HAVE YOU FULL LENGTH SIZED THEM THEN FIRE THEM TO THE NEW CHAMBER AND NECK SIZE THEM AND SEE IF THERE TIGHT.MAKE SURE YOU BUMP THE SHOULDER BACK 2THS MEASURE THEM WITH A HEAD SPACE GAUGE

You have a brand new virgin barrel and your complaining its too tight, someone here is going to have to start teaching tight barrel education................

1. Wash your hands and don't get any salty sweaty fingerprints on your expensive Mitutoyo vernier calipers.

2. Measure a fired case and bump the shoulder back .002

WARNING: If your brass stays long and hard over four hours, call a gunsmith.
DO NOT take the situation into your own hands.

A few years ago, on my 25/06 AI, I had this problem. The bump die would not bump the shoulders back, even with full shell holder contact when cammed over. The solution was to grind the shell holder down, or lap it down using a flat surface.

I think Redding makes different shellholder thicknesses too.

They only make them longer... not shorter.

My first question would be: are you using brass that was shot in the old barrel, or are you using new brass shot in the new chamber? Often brass that has been shot several times in a chamber that is larger than your current chamber cannot be resized enough to fit the smaller chamber. My first suggestion would be to fire form a few pieces of new brass in the new chamber. Then see if they chamber easily without sizing them. (An oval chamber will not easily take a fired case). If they chamber easily, resize them and try to chamber the sized cases. If they don't chamber easily you will then know that it is the sizing operation that is the problem. I realize that you are using bushing dies and assume that you have a bushing that is just sizing your brass enough to hold the bullet with the proper amount of tension. If, however; you are over sizing the brass and not lubing the inside of your neck, the expander ball may be pulling the shoulder/neck junction forward as you remove the case from the die. You then go through the same process when you seat the bullet. Hopefully, by eliminating one cause at a time, you can solve your problem.

I have a 22-250AI and my problem wasnt bumping shoulders ,it was the no turn neck that was the problem. So I just turned the neck for a light clean-up and it fixed the whole problem and they chambered really hard and I couldnt open the bolt either.

I had the same problem that Jon did. My reamer was ordered as a no turn neck, and was just a little too tight for no turn. I'm turning about .002 off and they chamber and shoot great. I wish that I could chamber factory ammo, but the rifle shoots so well that I don't want to change anything. You might want to do some measuring, this could be part of the problem. Lightman

Greetings Catshooter,

Thanks for the heads-up.
