i'va just found an article about rate of twist and the proper bullets for that twist. i own a savage 22-250 with 1 in 12 rate of twist. so according to the formula i found, my favoritev 50 and the 55 gr.hornady v-max bullets will work best in a rifle with 1-9 rate of twist and not with mine. so what is the most accurate bullets for my rifle? do i really need to stay with 45gr. bullets or less? by the way i'm new to the reloading thing
L=(150xDxD)/T
L= LENGTH OF BULLET IN INCHES
D- BULLET DIAMETER
T=RATE OF TWIST

Twist rate is only one part of what stablilizes a bullet. Rpm is what your really after. Shoot a high velocity load in your one in twelve, and see if the bullet you like stabilizes, I suspect it will. The 50 to 52 grain bullets should work no problem in your one in twelve at high velocity.

You can stabilize the 50-55 gr bullets with no problem. I have a 1:12" twist in my .223 and it shoots the 50's at 3350 fps into the .3 MOA range out to 300 yds. Most .22-250's have a 1:14" twist and regularly shoot bullets up to 60 grains without problems. Hell, I shoot 240 gr. SMK's in my Tomahawk and the skeptics said it wouldn't stabilize. Like S1 said, the speed plays a much greater role than you would think. If it won't fly straight, DRIVE IT FASTER...

Sambo,
Seconding what they said, it is about he rpm's. Just more examples for you: I have a 22-250 in 1:14 twist and the most accurate combination I found is the 55gr. V-max in the low 3700fps range. So I am sure your 1:12 will stabilize them. I also have a 220AI with a 1:16 twist!, and it can also stabilize 55gr. bullets, but velocity is 4230fps. If you want any load data let me know.

The 22-250 is just a Remington Sendero 26'' SS fluted barrel.

RL15 34.5gr. ~3650fps
H380 38.0gr. ~3750fps

These were the most accurate loads. You can use more RL15 than that, but the 34.5gr seemed to shoot the best in my gun. I live at 6700ft so depending on your elevation the velocities will varry a bit. I prefer to shoot the RL15 over the H380 because H380 varries with temperature more. If you are planning to shoot deer or antelope with it the seirra 55gr. BTSP works great with the same loads and ballistics are near identical.

The gun is now a 22-250 40degree, I would highly suggest making the modification. I can now shoot in the 3900-4000fps range with better accuracy, and I get about 15 reloads per case.

Hope this helps.

This is an older thread but I was doing a search because I am thinking about purchasing a 22-250 for woodchucks. 1-14 twist.

I thought there is some good information here. Not just bullet weight but bullet speed.

Comments are appreciated.

I shoot the 55 gr v max out of my model 70 stealth2. It likes 39.5 gr of H380 @ 3905 fps. 1/2" on most days, less on good days and a touch more sometimes.

My Sako Finnlite 22-250 shoots the Hornady 55gr V-max with great accuracy on GH's.

the Savage will easilly stabalize the 55 grain Vmax, and will be border line on the 53 grain Vmax. Best bullets I've found so far in the Savage is the Sierra #1365 at about 3550 fps using IMR 3031 powder. 2015 didnit seem to work nearly as well in the three savages I've owned or own right now. Yet the powders are very similar. The heaviest bullets I've shot were 60 grain Hornadays and Sierras. The Sierras seemed to shoot better, but not as well as the 55 grain bullet.

Right now I'm in the middle of working up a load I didn't think would work since my 22-250 has 1in14 twist. (actually it shouldn't work according to conventional wisdom).

The load is 53gr vmax
40.5 gr biggame
rem 9 1/2 primer
Nosler cases

gone through several powders, several different primers, and I'm now working up to 41.5gr or until I see a hint of pressure. So far it's shooting 1/2moa or better and seems to like being pushed hard, the only down side being that wood (maybe bullet fragments) from the target mount tear the hell out of the paper so you end up walking down range to check group size. but since this load is fully intended to scatter Pdogs and gophers I'm not complaining. :cool:

The 22-250 is a blast to shoot any time, but if you really want to unlock some performance doors get yourself a fast twist barrel of 1:8 or 1:9 and fire the big .224 bullets like the 70 gr VLD, 75 gr amax, 77 gr SMK or the 77 gr hybrids to name a few. With the right load combination and barrel you can push them around 3200-3300 fps safely. It's worth it for the wind resistance alone with the tiny .224 caliber.

The fast twist 22-250s are chuck splattering machines at long range.

I shoot a 6/250AI with a 1:8 twist barrel. It'll push 105Amax bullets at just under 3100 fps (very hot), and really gets the job done at about 3030fps. (mid twos and very low threes). Cases are simple to form out of 22-250 brass or better yet generic .243 brass. Dies were made from a .243AI sizer and a 22-250AI seater with a reamer run thru the neck of the sleeve. (.2775") I hand reamed the bore to .265" and then finished it with a custom ground reamer that was .277. Took about thirty minutes and a slight bit of elbow grease. The size was even easier as I cut off the .243AI die to the proper length in a lathe.

Lots of misinformation here, by comparing the 223 and 22-250 with their twist rates. A 223 with a 10 twist shoots 69's a 22-250 with a 12 twist shoots 69's.

For the 12 twist 22-250 you can shoot the 34 Grain dogtowns all the way up to the 69's. I know I own and shoot one.

The most accurate is the long 60 grain V-max @ 3700+ fps.

The 69's from a 22-250 must be shot at 4,000 elevation to work, as the twist is bordering stability.
