Im a southpaw and working on a rifle that will be a mirror image of the Remington 700 VS-- it'll be a copy of the Gen 1 in short action which lots of folks still call 'sendero' but they aren't technically.
Anyways-- cartridge is 22-250AI, barrel length will be 26" @ .830 (Remington Varmint Contour) planning to shoot 75s, 80s and maybe try out the 90s if they'll magazine feed (if I need to add a wyatts extended internal box I'll do that).
Barrels that are available: Brux 1-8 Krieger 1-8 Bartlein 1-7.7 or 1-7 (5R rifling)
Talk to me on advantages / disadvantages.

Any will work pretty good...don't see any real advantage of going over 80 grain bullet and a 1-8 will stabilize it...

Bolt gun running aics mags with zero issues. 90's are running 3240fps. 80's are a bit slower at 3124fps as I tried a slower powder but it's killed varmints and deer just fine.

1:8, or 1:7.7
I run 75 gr A-Maxes at 3200 fps out of a standard .22-250, 1:8. If it were me in your shoes, I'd go with either of those twist rates I listed, and run 80 gr bullets. I'm thinking an ELD-M will do fine on varmints.

Since you mention the 90 grain, that's the bullet you have to build around, since it's the heaviest/longest of the options. It will work with a 7" twist, but a little better with a 6.5" twist. I'd run a 7" twist.
A standard 308 mag will feed any bullet you want and still be well under max COAL for those mags in a 22-250. That 80 grain VLD Target would be AWESOME in a fast 22-250 round. I have thought about doing one of these also.

Standard 2.85" for those mags? I believe so. I've got a few with no bind plate and a few with them. Also got a few magpul which are as shipped and it works with all of them. Running a 22-250 which is very similar in case length you'll have zero issue's as Chad mentions.

Why do you want to shoot 90gr bullets out of a 22-250 at varmints? I just want the ability to shoot them at varmints and targets, especially if they are a long ways off, I can maintain good velocity, and much less drift. Also opens opportunities for deer / hogs. I figure setting up for the heavy for caliber bullets will make 70-80gr a cinch if I go lighter/faster.

Yes, Chad brought up 80's. I was just pointing him to another 80. Berger is no longer King of BC.

Light, very fast, and explosive bullets have always been considered the ideal for varminting.

Light, very fast, and explosive bullets have always been considered the ideal for varminting. I always felt that way. Then I bought an 8 twist 22-250 and started shooting them with 77 grain MKs. They hit with authority and I can't see them moving any slower.

Light, very fast, and explosive bullets have always been considered the ideal for varminting. I know. But there are other options, that's my point. I've used as light as 45 gr in .22-250, in the past. Now I'm loaded with 75 gr. I wanted to be able to hit prarie dogs farther out, in panhandle wind, and they do do that better.

I find it interesting, I've always not liked the 22-250 (as much, that is) because of the slow barrel twist rates since you couldn't shoot the heavier 22 cal bullets, like even the 68/69 grain or 75/77 grain. I always thought the round was handicapped because of this reason. I have always thought a 22-250 would be ideal with an 8" or 7" twist barrel. Others think going to a faster twist is a crazy idea. I find that interesting. It's a near perfect round for loading the heavy bullets. The cartridge is short enough to fit and feed out of any standard 308 magazine, even when seating the 80-90 grain bullets out long. There's no feeding issues with magazine room to deal with. The only lacking was the barrel twist. Sure a 55 grain is fast and flat, and I'm sure will kill a yote dead. But beyond 200-300 yards, it will lose too much speed and have an insane amount of wind drift. Stepping up to the heavier bullets will greatly improve the performance of the round for longer shots, and still work perfectly on varmints, and even deer. Just my

You're right Chad. I shot the barrel out of a 1:14 twist shooting 55 gr SGKs at 3780 fps MV.
I went to a 1:8, and loaded 75 gr A-Maxes at 3200 fps MV. The 1:8, and 75's was a game changer! Much longer range capability, and much better at bucking the wind.
Bout got that barrel shot out too. Thinking the next one will be a 1:7.7 and load 80's.
