22-250 Brass

[H2OBUG]

I just started loading for the 22-250 and I have some new and some used brass the used brass is Winchester and R-P-- I am finding that the R-P brass seems to be thiner and the brass seem to be springing at the sholder in my die. I am putting a good FL size on this used brass so it will chamber in my gun with no problem. As it bottoms out the brass is springing back rather than pushing the sholder like it should.

It will chamber but it is a bit tight

Scrap it or go ahead and use it- it is only 50 rnds

You could try annealing it.

The 22 250, in my experience, is the most challenging of all my varmint calibers to size due to the tapered case design. Over sizing can cause excessive headspace and under sizing can cause difficult chambering.

It's the one caliber that I will not use fired brass from other rifles because of chambering and sizing problems I've experience using such brass. Even with new unfired brass, I've encountered some problems so I purchased a Wilson Case Gage to set my full size die to verify the optimum sizing.

After firing in a specific rifle you can neck size to minimize case stretch of successive reloads but you should check the sized cases after a few reloads with a Case Gage to verify that cases have the proper headspace.

It sounds like the "spring back" that you are describing may be due to the brass being fired in a larger chamber than yours since you're experiencing tight chambering after reloading. Turning the die down further may correct this but almost may result in excessive headspace. This is why the Case Gage can help you set the die for the best sizing.

My best advice is to avoid using "use brass" for this caliber.

A lot of times, before you start setting the shoulder back, you will actually make the case longer by neck stretching. Bump the die slightly & keep trying it till the feel goes away. If it's been sitting quite a while, it would benefit from annealing.

Having the same exact issue with two 22-250 rifles. I have the die set as low as possible and cant bump the shoulder any farther. The brass is tight in both guns. I was thinking about sending the die out or just buy a different f/l. The brass was only fired in each gun. I dont mix brass and guns so i know that is not an issue. Now after a few firings the brass for my vanguard is splitting necks. Makes me love my br.

K22 I think you may be spot on--
My just have to dump this 50 pcs

If you're splitting necks, it really needs to be annealed. What I didn't mention because I kind of think of it as a given is that you NEED to lube the inside of the case neck when F/L sizing. I use 1 shot lube with the case standing vertical. When everything is done, trimming, champhering etc, I tumble them in corn cob to remove any residue. I run both a 22-250 & a 22-250 AI with no issues.

I follow the same lubing routine on my brass and sometimes i use a little imperial or hornady sizing wax. The hornady has an anti tarnish inhibitor in it.
