Ive been toying with the idea of buying a 22-250 on a 700 action and the more I look the more I see barrels with fairly slow twist, lot of 1:12 and 1:14. Why is this? I understand using light bullets for varminting but what if youre looking to hunt something with a bit of mass to it or shoot a light recoiling round at significant distances? It seems to me there are a lot of really high bc and excellent quality 22 cal bullets on the market such as the berger 90 gr vld, and the 80 gr amax so why continue to limit yourself to less than 60 grains? I see a lot of these bullets winding up in 223s, my ar likes the bigger amax bullets in fact, but wouldnt putting a bit more oomph behind it be a bit better balistically speaking ie less drift and drop? I understand theres always loads like the 220 swift if youre looking for a bit more knockdown out a 22. Cal rifle but id like to stay within the confines of a short action and be able to find factory ammo fairly easily if I need to. Just wondering if anyone else has thought similarly or if I'm way off base and should just scrap the idea. On a side note im not intending to start a theological discussion on the merits of hunting with a 22 that horse has been beaten enough.

I have owned several .22-250AI with an 8 twist barrel. This is a great combination for reaching out with a 75 or 80 A-max. Rockchucks will fly at 500+ yds. I would not hesitate to build another one.

Very interesting. How fast can you sling an 80gr bullet out of a 22-250 with a 24" bbl? As far as hunting with one, there are some pretty impressive 22 cal bullets made to penetrate after expanding. Concerning down range energy; it has a bunch more than the 32 Win SL (looks like a 327 federal pistol cartridge) my great grandfather fed the family with during the depression (the real depression).
I think you're on the right track. I'll be setting up a 223AI with a 7.5 twist as a long range plinker.
A lot of people pass right by the 22s, but the fact is an 80amax @ 2900 is at least as good ballistically as a 308.
Don't know what speed a 22-250 or 22-250AI can achieve with the 80+ bullets, but I'd expect a bunch over a 223 or 223ai.

That sounds like a good path to take, what sort of barrel life are you getting with that set up?
Probably not that great. I've only got around 800 rounds on the barrel. It's still accurate, but I'm not sure how much longer it will hold up. I should really lower the powder charge because maybe 1 out of 15 rounds has a hard bolt lift.
My best load was a 75 A-max at 3150 fps. It would shoot in the 3/8 range and made several coyote kills at over 500 yds. The great thing about the A-max is the fact that they will expand at almost any range. This rifle was used mostly for hunting and was never overheated. The barrel went for over 2000 rounds before it started to go south. All in all a great round.

That's the bullet and velocity I get from my 22" 1:7 223AI...its the tits.
Id step up to a 243 instead of jacking with a 22-250ai etc you get pretty much same FPS etc without fire forming brass etc.
If looking for light bullets run 1-12 with 55-60 gr vmax . I run
a Bullberry custom Encore with 22" barrel in 243 and get a tad over 4000fps with 55gr vmax and shoots well under MOA to 400yrds.
Or load 75gr or so should be able to push them 3500 or better out of a 243 .

Wouldnt running the same weight bullets in larger diameter be less conducive to good shooting though. All other things equal the smaller diameter should have the advatage as far as ballistics coefficient is concerned. I can see shooting a 243 to lauch larger grain weights than the 22-250 but why bother using it for say the 55 to 80 grain weight projectiles? It seems your going to burn out a throat much quicker running a hot 243 than an averge 250. I could be wrong and if so please educate me
That is right on the money. The 75 or 80 A -max have a great BC and that is the logic behind the whole concept.
