22-250 witha 8\" twist

Well I went and did it. I took my old 788 22-250 into a smith to see what we could do about the barrel. I was not sure if it could be just set back a little or would need to be replaced. Well he took one look at it and said he has not seen many barrels that had been shot out more than this one. I told him I had thought that might be the case as it is over 30 years old and has over 3000 rounds through it, he thought closer to 5000 and he could be right.
So now it is getting a new 28" barrel with a 22-250 A.I. chamber and a 8" twist. I am planing on shooting some of the Berger 75& 80 grain VLD bullets. I was wondering if anyone has tried them in a 22-250 A.I. If they have, what kind of velocity and accuracy they got out of them.
I would also be interested if anyone can tell what happens if I was to shoot some 50 and 55 grain bullets in a 8-1 do they hold together if you push them up over 36 or 37 hundred.
I know there are many other ways I could have gone with this gun and even got a new gun cheaper but then it would not have been my 22-250 from my youth. It is a bit of a project that should be back to me in about 6 weeks.
As always I thank you in advance for your input.

Re: 22-250 witha 8\" twist

i am pretty sure a 22-250ai wont feed thru the clip without some modification i ended up messing up a clip on a 223 ackly in a 788 trying to get them to feed
you might think about a 22-243 (standard)if you want more speed than a 22-250 i built one but it was on the longer action 788 it worked fine i think it was a 7mm-08 originally

Re: 22-250 witha 8\" twist

As far as what will fed through the clip I couldn't care less. For the kind of shooting i will be doing I will never use it. I have not used the clip on this gun in years. I allready have the project moving along as a 22-250 A.I.with a 8" twist. I was just wondering a little about what I might expect when I start shooting it. I am notlooking for what some one else might think would have been a better way to go. If it was not a 22-250 I would not feel right shooting this gun.
Some people don't feel right driving anything but a Ford so thats what they drive. Even if others are sure a Dodge is better. I am building a 22-250 because that's what feel right for me.

Re: 22-250 witha 8\" twist

Hi North i have a 22-250AI and have a 6.8 twist on it the barrel was originaly chambered in 223 so i could get a difinative velocity test diference after 150 rounds were fired we rechambered it to 2-250AI and re tested every projectile. i shot from 5gr BlitzKings to 90gr Sierra MatchKings through it the twist was fine for all projectiles in 223 but a tad har on the 55gr at max velocity on the 22-20AI. The 8 wist is much better for the 22-250AI and will shoot a 5gr Blitzking very well and you will not have any trouble with them staying togethor as long as yu dont try to push them past 4K. The 22-20AI in the 8 twist should also stabalise the new 90gr Sierra quite well so give it a go the fast twist on the barrel was to harsh on the 90's in 22-250AI but was fine with the other MatchKings. Be aware thet the 8 twist wil be very hard on the A Max's and Bergers because they have very thin jackets if you are et on using them get a 9 twist or you will blow them up in mid air. I blew the 75gr A Max'x up in the 6.8 twist when it was 223 so i did not try them in 22-250AI they would have never held togethor.

Cheers Bill

I can't speak to the Berget bullets at high velocity. I've shot Nosler 40g bt's to better than 4500 f/s in one of my 22 CHeetah's. Shot less than moa too.

North of 53 ,-welcome !!

I know what you mean about keeping a rifle the same ,i have a 25-06 that i've had since 1980.A friend recommended i make it a 257stw -it wouldn't be the 25-06 i've had for most of my life.
The 55gr bullets will do ok at high speed twist but the big 75gr a-max and berger vlds will spoil you.
There is a good bit of data out there -start w/full house 22-250 loads.
You'll probably get around 3200ish out of the big bullets.
You're old sweetheart 22-250 is going to be a longrange monster w/the AI + fast twist custom barrel.You'll be glad you didn't get another rifle once you send a few bullets down a custom barrel.-Best to you --Mike

Re: 22-250 witha 8\" twist

I have found that number of rifling has been more important than actual twist rate when getting the heavy Berger bullets to stay together.

All has to to with bullet baring surface compression. Make sure the barrel your getting is not a 3 groove design. A 5 groove is better and a 6 groove would be the best.

The fewer the lands in the rifling, on average, the wider the lands. This is what causes the problem. Make sure your getting a thin landed 5 or 6 groove barrel or you will tear the Bergers apart no matter what velocity you are driving them to in a 3 groove barrel.
