Rechambering a 22-250 to...?

[shinjin]

I have a 22-250 ackley improved barrel on a 98 mauser. I don't need it and its prone to misfeeding with those short cases unless I spend time I would rather be using to shoot PDawgs loading it carefully. So, I am considering a re-chmaber.
 
What can i rechamber a 22-250 to that is a longer case (solve the feed issues) and give me enough additional range to make the effort worth cost?
 
Its re-chmaber or re-barrel and then its 257 Roberts or nothing.

The biggest issue is going to be the twist rate. That would normally be a 1:14" twist for a 22-250. There's the 22/243 Milstead that pushes a 50 gr 22 caliber pill at 4250'ps but it takes at least a 1:10" twist. That round really shines with the heavier pills but requires a 1"9 or 1"8" twist. It has the same head dimensions and obviously longer.
If you rebarrel, consider the 257 Bob Ackley Imp. It's the best of the Ackley mods and can get to 2506 ballistics but uses far less powder and still have the ability to shoot 257 Bob factory ammo.
A few others to consider: 6.5x06, 25/284, 6XC,

 Shinjin, that case has a wider shoulder than a "normal" 22-250. There are a few 22 wildcats based on the .243 and 6mm case. ALL are barrel burners. You may get a thousand rounds thru them IF your barrel is in excellent shape bore wise. I'd find some one to REBORE it to 25 Roberts Improved. You'll have fewer issues and a lot more loading data. Plus NEW rifling to work with.

I would rebore in a heart beat if I could find someone to do it.
 
Contacted a large company and they declined saying Mauser barrels are PITA, but in more professional terms. Since the barrel is unmarked for Maker I couldn't argue him into looking at it. In the long run a re-bore by him was as expensive as a re-barrel by Shaw so it wasn't any savings.
 
Anybody here got a suggestion?

Have a you considered a spacer/ block in the magazine? Another option would be a single shot follower.That should solve the feeding issues.

[shinjin]

I  have a spacer block in the rem 798 and while it isnt the best solution it works.
Does anyone know where i could buy another?

[jeepmann1948]

Check out Numrich Arms they have the spacer but are out of the follower.I know some of the old gunsmiths cut the original followers down to the shorter length .

Can you set-back that barrel 2 or 3 turns if necessary?  To clean up a sloppy machining-rechambering job?
 
But going back to your first question/s,  I too would select the standard .257 Bob if not the 6mm Remington (standard), either with a 24-26in barrel!  If you simply want to park yourself behind a shooting bench, maybe consider a heavy barrel?
 
But if you you're used to hoofing it a bit, maybe pick a walking-varmint contour of some kind that you like?
 
If you don't like the case the 6mm and Roberts is based on (7X57 Mauser), then why not possibly consider the .25/06?  Or better yet ...... a heavier-barreled .270Win for varmint blasting? 

[shinjin]

I just ordered a spacer from Numrich.
 
Unfortunately they do not have the mag/trigger guard with the mag well set up for the short spacer. Somewhere in my growing pile of gunparts I HAVE a short follower and if that search fails someone is always selling them on e-bay.
 
So- before I re-bore let me try the obvious route. if that doesn't work for this caliber it might do me for a 308 or 7/08 later.

Ever consider just trading it off? Years ago I looked into rebarreling a 98 and restocking it plus a new triger--by the time I would have finished it --it would have been cheaper just to buy a ruger number 1.

  I had a bad chamber in a 25-06 some years ago. the bore was also a bit tight! I sent the barreled action to Clifford La Bounty when he was in Maple Falls Washington. He did an excellent job of reboring it to 280 Remington. There was some issues with his timing, but the gun has proven to be quite accurate. I do not know if he is still working or retired, OR where he is now.
