22/250 Twist - Which Is Better??

[waynewjw]

1:14 i.e. Remington, Ruger, Sako
OR
1:12 i.e. Savage

Anyone have experience with this calibre and can give me some advise as to which twist is better? I want to do some long range shooting 200 - 400+ yards.

Which twist will allow me to use a wider grain range in bullets?

Which twist will allow me to use a wider grain range in bullets?

The 12 twist will and a 10 twist would allow even more...

I have A Rem I am still trying to dial it in. I have been told that with a 1:14 twist you can not shoot any heaver than a 55g lead and a 1:12 twist you could go to 62g lead this is what i have been told the weight of leads may be +- a few grains

ive got a

pac-nor supermatch in 1-14, shooting 55gr noslers out to 1100 yrds at summerland...... BUT I am shooting an AI version at 4000 fps.......

Don't listen to Brad. That was an evil rifle doing evil things.

Next year, you better have enough up to go to the mile.

That bullet has to crash sometime.

Great stuff....

PS saying you burnt out your barrel will not be considered a valid excuse.

The tighter the twist the better, generally speaking for long range shooting in centerfire 22s. - dan

I've got a #3 contour 1-8" Rock on order. Can't wait to see what an 80gr. amax will do at 3300.

Nice

let me know how that rock bbl treats ya...... I went with pac-nor on my hipo .22 but i have a rock on my .338 lai....

So What Grain?

O.K. so it sounds like I should go the 1:12 or less twister. What is the grain range?

 

[bradtothebone]

well,

I would say.... in a normal .22-250 velocity, I would tend to lean to the 1:12. According to a very knowledgeable source, savage bbls TEND to be on the quicker side....ie 1:11.6 instead of 1:12, and remmys tend to be on the slower side, of course this is just a tendency. So if you wanted to shoot 55s or slightly heavier, definatly go to the 1:12 twist..... The others would be pretty much maxed out with 55s and MAY not even stabilize them adequatly.....

In case the ever make it up to Canada, Savage is making a 9 twist 22/250.

So you can have it all....

I've got a rock m24 tube on my .308 f/f gun and it shoots light out. Cleans up super easily too.

22-250 twist

there is no magic in barrel twist. a longer/heavier bullet needs a faster twist.
you will also find that the smaller bullets require the faster twist. lets compare a 22, 6.5mm/.264, 7mm/284 etc.. with long bullets:
a 223 at 80 gr needs 7 inch
6.5mm/264 140 grain need 8 inch
7mm/284 180 gr need 9 inch
and 308 175 gr or more need 10 inch etc...
It's all based on proportions as you can see.
so for the 22-250 you want the fastest twist if you want to shoot heavy bullets. I have a 14 inch twist on my 22-250AI and can only shoot the 55 grainers. I tried the 68 grain Amax and they don't stabilize. this means I can't hit a 2 foot x 3 foot target at 100 yds with the 68s but I can do dime groups with the 55s. I will try the 64 gr flat base Bergers because they are shorter but they might not stabilize.
If you go to the Berger site you will see they tell you which min twist is required for each of their bullet. Hornady also writes the min twist on all their heavy match bullet boxes.
