Anyone shoot a .22-250 with a 9 or faster twist? I shoot .223 with 75 grain bullets, but was thinking that the added velocity of the .22-250 would stretch out a little better. No factory .22-250 has a faster than 12 twist from what I can see, so a custom would be in order and I'm OK with that. Any thoughts? Anyone?
Fast twist .22-250

A few years ago a buddy was using a fast-twist 22-250 in F-class, now I could be wrong but I think he had an 8-twist barrel. I do know he used an 80 gr. bullet and with good success.
I don't know what his barrel life was like but he is a very competent and meticulous competitor and does all his own rifle work.

Might be a good option to shoot the 90gr VLD's.
Barrel life may suffer but if you could get the accuracy out of it it might give the 6BR a run for it's money. Those 90gr (@ .281) have a better BC than the 6mm 105 VLD's (@ .272)

Savage makes a factory rifle chambered in .22-250 with a 1-9 twist rate http://savagearms.com/12Varminter.htm
wholesale had one in-stock a few weeks back when I was shopping for a new .22-250
Oh and Barrel life with a 250 is only an issue when shooting over 4000fps so don't fall for that crap. Shoot a 70gr VLD over 32gr Varget and the pressure wont be much more then a .223 shooting the same bullet. You will have about 400fps more speed with the 250 and the barrel life will be virtually the same as the .223.

I'm thinking about one of these as well...a fast twist 22-250 that is. Everywhere I've read, people are saying that the barrel life will quite a bit shorter then with the 223. Seems to me that more powder has got to equal more heat and that means more wear...or at least having to let the barrel sit and cool more often.
The pressure created by burning the powder and the speed at which the bullet travels also determine's barrel life. Check out the pressures created by buring the same powder in each chambering utilizing the same weight bullet. You will see the .22-250 and the .223 are quite close when you start shooting heavy bullets.
The life of a .22-250 barrel when maintained properly and not exposed to 4000+fps loads will last well into the 3000+ round range which makes it a non issue.....I would be more concerned with the cost of ammo/reloading between the two if your going to shoot 3000+rnds in a short period of time......How long would it take you to shoot 3000-3500rnds? maybe 5-7yrs? is barrel life really a big deal?.......NOPE
save your pennies and buy a pre-chambered barrel from mystic for $400 when you wear the factory one out. I'm sure we could all save $400 for a barrel over 5-7yrs....
Bergers website reccomends a 7" twist for the 90gr .224, I'd like to try a 220 swift. Wonder what velocities are possible?
Would the 80gr sierras or the 90 vlds be better? I assume you would need a 1-7 or 8 twist? I would like to can out the barrel on my browning, it shoots dam good with 55s and 1-14 factory barrel. What do you thing Richard???

There is a member at range built a 22 250 on a savage action witha 26" custom barrel with 1/8 twist he is doing okay with loads with 75 to 80gr bullets but nothing special .500" groups his choice of powders are not what I would use, the ball powders are great with small bullets but in 223 with 80gr The powders i find work best are VARGET,RL15 VT 540 550. and he should have got a 1/7 twist and shoot 90 gr bergers or JLK with high BC
But remember when you go with 22 250 in F class your up against the big guys with 6.5/284, 284,7mm wsm etc all shooting 180gr Bergers. unless you get a day with very little wind you won't run against the big boys at 1000y.

If you are tempted to use your .22-250 for wolves or big game, the fast twist is a better option for the 53 gr TSX. I loaded some for a local fellow after suggesting that the TSX would be better for caribou than the lead core bullets he currently used. Actually I told him to get the 45 gr, but the 53s were all he could find. When he sighted in his group was poor, and the bullet holes in the target showed lots of yaw, so back to bulk bullets he went.

The 90gr Berger VLD WILL stabilize in my Shilen 8 twist 223 going pretty darn slow. Shot out to 1200yds just to make sure it didn't tumble. Did just fine.
However, a 7 twist is a safer bet incase you get a slow 8 barrel. Or shoot at sea level on a hot humid day...
I will be getting a 7 twist 223 and 22/250 in Jan or so. Both will be for F class Savage rifles. The goal is to make the 223 better then the 308 in F T/R and the 22/250 viable in F open.
With a possible top speed of 3100 to 3200fps, the 90gr - 22/250 set up will equal a 6.5-284 with 140gr VLD's all the way out to 1000yds. Barrel life will be as short but recoil will be cut in half.
That is the theory, now to see what happens when we start making noise.
For the 223, H4350 is working well. For the 22/250, I would use H4831SC.
A fast twist 22/250 would be a lot of fun and will do everything a 223 will do but 300yds further.

Will definitely post my results if and when I get to shoot it. Hoping it will not be too cold this winter.

I'm gonna try this Rem barrel nut idea and ordered a 26", 1-7, 22-250 tube. Let's see how far one of these 80g, 22 cal bullets will go!! The yote dogs up here at work might be in for a little surprise this late winter too
I can't believe this thread came up the same week I thought this idea up....

In my eight inch twist 22-250, I can get over 3300 fps with 80 grain Sierras. Accuracy from the Mcgowan barrel is fair (about 5/8 moa). The best velocity has been achieved with 4831SC. This might be a good candidate for Reloader17.
Contrary to previous statements, I doubt that barrel life will be the same as in a 223. There is no free lunch. Barel erosion is affected by pressure, velocity, the temperature of the powder gases and the length of time the barrel is subjected to the high velocity/temperature gases. Larger powder charges produce more gas and maintain high pressures for a longer time. This is why 7mm Remington magnum barrels don't last as long as 7x57 barrels. Regards, Bill.
