22-250 Ackley loads with a 1-14 Twist

[458win]

Anybody know the heaviest bullet that will be stablized in a 14 twist? I purchased a custom 22-250AI with a 26in heavy shilen 1-14 twist barrel. So far I have only fired Winchester's 22-250 Varmint Pack 45gr JHPs when I was home on leave a few weeks ago. Would the 60gr V-Max's work or should I stick with 55's or 50's? I sorta can already hear the advice of shoot'em and find out, but when I get home I don't imagine I will have much time for experimentation. The main use of this gun is going to be for ground squirrels and chucks out to 6-700yds(hopefully). Thank you in advance!

I'm having my 22-250 rebarreled and considered having it chambered 22-250 AI .

If memory serves the 60 gr will stabilize ,use the powder that gives you good velocity.
I'm not sure how accurate it will be at the ranges you mention.
LB from huntmasters can give you some good info. on the 1-14 ai varminter.I hope this helps Mike

I have a friend who built one(22-250 AI) with a 1 in 16" twist.It would stabilize 55's ok with the added vevocity of the AI chamber.I do think it will work if you load it warm enough.

Your pushing it in a 1-14 twist with a tipped 55 gr bullet. Its worth a try but don;t buy alot of them as I suspect you will have stability issues at long range. I would say the 60 gr will not stabilize.

That said, try them, stranger things have certainly happened.

I will also say that 700 yards with a 55-60 gr pill will be difficult in anything but perfect conditions. At least if your looking for consistant hits at that range on small targets.

If I had to pick a bullet to use in that combo it would either be the 50 gr Ballistic Tip or the 50 gr Blitzking. I use the Blitzking in my 25" 22-250 AI and get 4000 fps with 3/8" groups. It is not however a 700 yard rifle. 500 yards is about what I limit it to and then go to something with a higher BC bullet.

Let us know how it works for you.

My 220 swift is a Ruger Target with a 1 in 14 twist. It shoots 55g BT's and FMJ's in the .3's. I have shot my 55g BT load at 525 and I was still getting MOA groups. I was also wondering if my swift would be able to shoot the 60g vmax because of the 1 in 14 twist. I do not want to buy a box just to see, I would rather know for sure. With the velocity of the swift, which is the same for the 22-250 AI, I was hoping it would work, but I have never tried it. It would be nice to shoot the heavier 60g though because of the little higher BC and wont be such a barrel burner.

I have been using a 22-250 Ackley for quite a few years, now. It has the 1-14" twist and is 28.5" long.

Starting out, I settled on a 52 berger, more than satisfied with the accuracy and velocity was in the neighborhood of 4400fps with a full load of H414.

The first time I took that gun to AZ, I missed about eight coyotes, shook my head, put it away and used a different gun. Turned out that those beautiful groups at 100 yards were not making it to 200! The bullets were exploding somewhere beyond 100 and wouldn't even print on paper, at 200. Guess I didn't do ALL my homework? When I asked the guy that did the work, he claimed that he had suggested heavier bullets, but I don't remember that? From that point forward, I have been very opinionated. A 22-250 Ackley performs best with HEAVY bullets; period.

Anyway, it turned out that there were a half a dozen rifles in our little neighborhood and they were all using a 65 grain Berger, which was brand new territory for me. The BC is so much better and the velocity is almost beyond belief. I get 3925fps and it is the best coyote bullet I have ever used....and I have used a lot. Bears repeating: 3925fps with a 65gr. bullet. Steams through both sides, bang/flop. Would do the same with chucks, but it is actually too much gun for ground squirrels; not that it wouldn't work, just a waste of performance.

You can't buy the 65 any more, but they built a 64 grain mold, and I am presently using a 65 grain Starke, which Clint made for me, special. If you use the 64 Berger, don't get the MEF.

What fifty said is probably true, it is not the best choice for 800 yard live targets, but I don't go there with this gun. It's just a serious, dedicated long range coyote rifle, as good for that purpose as I have ever owned. For high volume critters, I'd consider something else, faster twist perhaps, but within the stated perameters, it will perform beautifully.

My load is 44.0 grains of H414 with the fed 210Match primer.

Good hunting. LB
