22-250ai ?

[calib]

should be getting my barrel any day now

 

[calib]

well i found out my barrel will be here with in the next two weeks

 

[calib]

would even a 1:10 or 1:9 get me into some real decent .224 caliber projectiles? i dont want the heaviest, but maybe would be willing to go half way to keep some speed and gain some ft/lbs.

if i found someone wanting to i would even trade a barrel

1 in 9 will get you up to the 68-69 Hornady and SMK as well as 70vld. May or may not be able to stabilize the 75 amax. Buddy has a 22-250 with a Shilen 9 twist and it shoots the 75 amax very well but others have reported that they don't work. I went with a 1 in8 to make sure that I could stabilize the 75 amax as that is what I wanted to shoot. I don't think that a 10 will do much for you over a 12 twist in the 22 cal.

thanks lrpv

what was the reason you wanted to shoot the 75's? what kind of performance are you getting

 

[LRPV]

I load for some friends. One wanted to build a rifle so i looked around and decided the 75 a Max would be to play with. He had the 1/9 22-250 built. I think we are running them around 3200 but can't remember exactly. 2 years ago he was consistently hitting p dogs between 6 and 700 yards with it. It shoots flat and straight and seems about as good as it gets without going to a hot 6 mm. The bullet has great splat factor on pdogs but I haven't seen what they do on coyotes. I put a 26" varmint Criterion ackley 1/8 on my Savage repeater and haven't shot it much yet but fire forming with buddies loads are producing groups around .25". Needless to say I'm pretty happy with it considering how bad the project before it ended. Buddy is a Remington man and has since had two identical 700s built in 22-250 ackley 1/8 with 22" barrels in lvsf stocks. One snow camo one in brown. We haven't shot anything but fire form loads yet in any of them. I use a 22-250 tikka t3 lite shooting 50 vmax with a cds Leupold and it works great for me on coyotes out to 400 yds but it seems to be running out of gas past there. The tikka won't stabilize 53 vmax so I'm stuck on the 50 for it.

that 75 v max sounds like it does pretty good. i would like to hear what it does to coyotes. that could take over my 243 ai shooting the 70 grain ballistic tips, though it wouldnt have the same power.

 

[LRPV]

Energy would depend on some variables. Running numbers with a 70 Sierra blitzking with a guess of 3600fps and the 75amax at 3300fps (which I'm fairly certain I can get to with the Ackley). The 70 grain .243 bullet will have an energy advantage from the muzzle to 100yds but just a little past 100yds the 75 will take over in energy as well as the advantage of wind drift it already has from the muzzle.

 

[calib]

you are rite lrpv i just ran some numbers on my sierra suite and that 75 (.224) out does the 70 (243) pretty easily. i ran the 75 at 3200 fps and the 70 at 3650fps and got about 50yards difference in the transonic region and the power noticeably drops on the 70 grain quick after around 500 yards or less

Hi Calib,

Don't mean to hijack your posting here; but since we're on the subject of 22-250 AI Loads.... But I am going to start working with my 22-250 Ackley again now that its spring break and I'm finished with school, for good (looking for work).

This barrel has been the biggest PITA of any I've experienced. It's a 1-8" gain twist Bartlein (only 3/4" gain).

I've tried:
Bullets: 80-A-Max, 69-SMK, 65-SGK.
Powders: RL-22, H-4350, H-4831sc and RL-19.
Primers: Fed-210M and Russian.

Tomorrow I'm digging deeper into my powder stash. I'm going to try some IMR-4350 and trying H-4831sc again with CCI BR. I have loaded up some 75 Hornady BTHP from -.025 to +.015" seating depth.

This is a proven platform besides the barrel.

Looking for suggestions on other powders or bullets, for such a picky gun. I might be making a visit to BulletSamples.com.

flybuster,
you wouldnt happen to be trying to shoot this gun at the sportsman's challenge would you?

i dont mind if you chime in here. i wouldnt mind hearing some more about the heavier bullets anyhow. i am thinking of trading my 1:12 for something faster, i may need it to show up first. i would like to see what the light bullets do on things and group wise.

I set up this gun so that I could have a flat shooting long range gun for coyotes/varmints, and planned to use this on varmint steel matches. But the gun just doesn't want to group under 1" most of the time.

I chose the high B.C. 22 caliber bullets over 6mm because they are somewhat comparable in B.C. to a 105 but I can launch them faster with a smaller case. I was particularly interested in the A-Max because I thought it would be highly frangible, and perfect for varmints and coyotes. Plus the lighter recoil of the 22 cal would make spotting hits easier.

The gun is a Tikka T-3. The original barrel is a great shooter, but I was just limited to lightweight bullets. Love this Tikka, great handling rifle, nice trigger, smooth bolt.

You bet, If I can find a load for this gun that's what I'll shoot!

Mine loves H-4350 and 75 hunting VLD's at 3425. I'd take a look there.

22-250 prefers RL15 for 50-53 gr bullets

RL15 is superior to Varget in the velocity department adding an easy 150 fps and maintaining excellent accuracy using 50-53 gr bullets
I beleve that bullets in the 55-60gr. weight might be more ideally suited for Varget - I'm not sure.

For anyone with a factory 22-250 should try RL15 for outstanding results for 50-53gr bullets

My standard factory 22-250 TIKKA MODEL 595 MASTER SPORTER loaded with Berger 50 Varmint provides an avg. velocity of 3830 fps and shoots in the mid 2's @ 100 ys.

The 22-250Ackley loaded with RL15 and 50-53gr bullets should generate 3950 fps

 

[CoverDog]

+1 for RL15.....I used IMR4320 in a 22-250 for 30 years. Three years ago I went and tried RL15, about 100fps faster and better accuracy. My current gun is a Savage Predator and this is what it likes:

55gr SBK over 37.1gr RL15, CCI BR2's, OAL to Ogive 2.098 which is a .005 jump, avg. 3725fps from the 22" barrel.

The last 3 shot group before the gun went into the safe was .156"

thanks for the info guys,
i looked in my powder stache and have a lb of rl15, i may just have to try that and keep it in mind when the ackley gets here.

well good luck with the loads i am hoping some good info comes throu as i am looking into this now. i love the 243 ai, but if i can do better with less i may be changing my game a bit.

Thanks Alf,
I will order some.

 

[LRPV]

I am using H-4350 as well. I thought about trying something else like H4831sc or even Hybrid 100v once I got fireformed but I'm gonna stick with the H4350. I'm getting too many different powders on the shelf anyway.

I think I've found the solution to my headache. Before I switched primers I was using Federal 210M and Russian primers. I was averaging groups at 1" and I was getting severely disappointed in this barrel.

Today I tried three groups with CCI BR-2s and my averaged groups dropped to .5", so I am headed in the right direction by switching primers.

It's amazing how much difference a change in primers can make sometimes. I think if I keep at it with my load development I can really make this thing drive tacks, at least now I can breath a sigh of relief.
