How do I get thick neck brass?? to enable turning for factory chamber

[Ogre6br]

I'm looking at a way of getting thick neck brass for a mates 22/250

he has a factory chamber gun

We want to neck turn the brass to get it concentric and a better fit
But if we turn factory Rem brass we end up with huge neck to chamber clearance with only just a little neck cleanup less than 50%
We are wanting to get a good 75+% cleanup but if we do that the neck clearance is monsterous and the amount of brass work when re-sizing the necks will kill the necks in a short amount of time.

With the 6+ months of wait time for a Gunsmith to do even simple work over here in AU like doing a cut and shut with a match/tightneck reamer

We are investigating brass options so we can get a fitted neck in a factory chamber.

What can you guys suggest??

thanks
later

When I purchased my Savage LRPV 22-250, I ordered Norma brass for it and run into the same problem, so to speak. I wanted to do a very light clean up, say maybe .001 or so. But after firing the rifle a few times I discovered that the brass was way too thin. After looking thru some existing Nosler onhand brass for a couple of other calibers I realized the neck walls were thicker in comparison to other brands so I ordered Nosler's brass hoping that it would have thicker neck walls for the 22-250 and it did. I was able to make it work with the Nosler brass. As far as I can tell Nosler brass has thicker neck walls than any other brass out there except of course for the short and super short magnums. I hope this helps. Bill

It won't have the correct head stamp But,you could take a larger caliber case ex. a 243win,250Sav, or 260 etc.run it though a file type trim die for the 22-250 anneal,re-size,and turn.That should thicken the necks up enough for ya

Been down that road with a 308. Tried 358 win necked down. It was a waste of time with my rifle. With a stock chamber I got better accuracy just cleaning up the necks and leaving the loose neck fit. I believe that the extractor pushes the case forward against the shoulder and the neck probably does not touch the chamber so it did not assist in aligning the bullet. Just my opinion. Good Luck.

I posed a similar question a while back. The thread # seems to be 2592148 or search "Making Case Necks Thicker" I did not make any progress to date. I thought it was a good idea too.
Good luck, Peter.

Another question I have is:
What is an acceptable method of measuring the chamber neck diameter?

Making a casting of your chamber with something like Cerrosafe - it's a low melting point alloy that actually expands as it cools.

Easy enough to do once you order some up.

Short of that, the only way I know is to measure the reamer used but even that's not always as accurate as you might like.

Many years ago, Shooting Times magazine had publicised a national shooting contest using factory Browning A-Bolt rifles.

The winner was their own Rick Jamison.
He used a Browning A-Bolt chambered in 22-250, he used 30/06 cases to make the 22-250 cases.

It gave him the thickness to make a light cleanup of the necks. The groups were impressive so it may be worth all that trouble.

Not a hi-jack. PETE you were trying to get thicker necks for your .222 Rem their just aren't many cases that fit the base specs of that cartridge. You have the 221FB too short,.223too close in dims. to make a differance,222Mag also possibly too close in dims to work properly.Unless you want to put REAL work into it by Swagging the bases of a larger case and modifying the rim/groove area as well

Why would any manufacturer make brass that may or may not fit all factory chambers? They have no idea what rifle the brass will be used in.
If you want to do it right your going to have to rebarrel with a tight neck chamber. In addition to the chamber you'll get a superior barrel.
I waited 9 months for my custom 6 BR. The Krieger barrel took 8 of the 9 months to procure.
Measure all brass and put a lite scratch on the high side. When loading your rifle always load with this mark in the same position. This is the only way I know of to achieve some mesure of consistencey.
If you have a ball micrometer you can safely turn your necks walls down to .012".

So, if you resize your brass and come up with "fat necks" that are NOW snug in the neck area, consider a chamber "neck ONLY reamer". Had issues with reformed brass ending up with "fat necks? Rather than turning each and every case necks, just got myself a chamber reamer with the size "neck" that I wanted!! Already have the chamber cut? Do ONLY the neck area to where YOU like it!!
Like the chamber you already have but don't like the thought of turning necks???
Chamber "NECK ONLY" reamer is your friend. Doesn't touch the reamer "body", just the neck.

You can buy basic 308 brass that hasn't been formed and try making 22-250 brass that might come out with thick necks.

When I made 350 Rem Mag brass from 7mm Rem Mag I had to turn a lot off the neck to get a loaded round to chamber.

What I would do is look for a brand of brass that has really uniform neck thickness and work with that. From there if I really wanted a snug chamber I'd order a tight neck barrel.
