22-250 to 22-250AI

[Mike in Oregon]

I'm currently in the process of buying a Winchester Model 70 Varmint 22-250. The gun dates back to 1993 to 1999 and looks to be a very clean rifle (I have detailed pics being sent this evening). The only concern is the unknown round count. The current owner has a documented 239 rounds fired. Before that is unknown.

So, here are my thoughts. By buying this gun it will kill two birds with one stone! First, I believe a 22-250 should be in every varminters arsenal. Second, I have always wanted a Winchester.

Now to the point. My thoughts are to rechamber to AI, shoot however many pcs of brass I think I might want (250-500), as this will be a rock chuck setup and dbl for PD's (if I ever I ever decide to make a trip to Montana or Wyoming). If it ends up being a shooting and I can develop an AI load, then I'll run with it as-is till the barrel life starts to go away. At what point I will rebarrel to a desired twist and already have my fireformed brass.

Right now, I'm thinking a 55-grain NBT, Blitz, Vmax or a 62-grain ELD-VT. If anyone has any info on the 62-grain ELD-VT, I would love to hear them!

62 ELD-VT in 1-14” twist?

IF, you want to SEE, the "Splodies" with, a .22-250 Rem., in an 8 to 9 Pound, Walking Varmint, BRAKED, Rifle, Use,.. 50 gr V-Maxes, 52 gr A-Maxes/ Bergers or, 53 gr. V-Maxes ( 12-14 Twist ), Pushed at, NO More than,... 3,600 FPS !
And,.. Set Scope for,. 18-20 Power, Max.
IMO,.. There's No need for, the Ai Version,.. Except to, cut down on,.. "Trimming" cases.
H-4895, IMR 4895, H-380 and Varget, are "Good", Powder choices in the .22-250 for, the sub 55 grain bullets.
Size the Case with, a Minimum of shoulder "Set Back" for, Best Accuracy in, the old 250 !
There's NO need to spend, a Lot of Money on Expensive Bullets to, Shoot PD's and Sage Rats !!!

62 gr vt don't waste your money, needs much quicker twist rate. I wouldn't even try the 53 vmax either. The old 52 amax shoot good out of 1/14's.

The brass in the ackley version will last a long time and they are super accurate. My go to is the 50 grain nosler bt for small vermin. 14 twist is plenty

Read my post closer. If I rebarrel, I will do what twist is necessary.

Ok got it.
Having done a 22-250AI I would recommend a 22 Creedmoor for a host of reasons.

Got one! I knew the CM would come up. Yup, have one in a Ruger No. 1 custom.

Know this: For maximum throat life, the longer the case neck couple w a 30° shoulder minimum I'll give you a tremendous decrease in throat wear.
Have a Bud who did pd's in the glory days, a week or two atta time w we'll smithed, well barrelled rigs. His 6mm Rem AIs always lasted longer than his .243 Als...ALWAYS.
He put together a long necked 6XC (.400") and had less than .007" wear after 700 rds of 107s at 2 nodes - high end 31xx and 33xx low side. He really likes to push things and the brass was beyond double digit firings.
If anyone wants to chat w him and get more precise #s, pm me.
He used Palma brass for the small primer rim strength.
He also tried weighting his 224s to see the air time. 16# and he still wasn't seeing it all. I know not at what power.
Itsa fun ride, enjoy it....

Mike -

Howdy !

RX :
If your rifle has a 1-14 barrel 24 - 26” lg barrel, I suggest you shoot H414/WW760 under
55gr varmint bullets…. whether FB or BT. These days, you might be more likely to find 6.5 StaBal…. another Winchester powder….. just 2 “ burn rate “ rankings “ slower “ than the first two listed.
I also suggest also, giving FED Large Magnum Rifle Match ( GM215M j primers a try.

You’ll likely want to do something about the ( factory ) trigger. None of my anti-groundhog / accuracy rifles have triggers rated in “ lbs “ pull effort. I myself like
1.5 - 2oz triggers for that, but hey….that’s just me.
