22-250 ack imp

[remingtonman_25_06]

I might have a chance to get a savage 22-250 ack imp with a 25" douglass, 1 in 8" twist.

I'd love to shoot the 75g or 80g amax. I would think it would be pretty dang good out to 800 yards, and if there was no wind, it might even do decent at 1K. It would be a coyote rifle is all, maybe 75g scirocco for deer for the wife to shoot.

What kinda velocity would I be looking at with what powders??

Would the 55g plastic tip bullets still shoot ok in the 1 in 8" twist?? Would still like to have that cool splat factor on little rabbits and squirrels.

What kinda barrel life would one expect if you were to shoot the heavies and not let it get hot and good routine cleaning??

Anybody out there shooting a 22-250 ack imp w/75g or 80g amax's lets here it!

Remy,

the 1:8 twist will be fine for the 55 gr BT. The 60 gr BT would be an awesome coyote bullet.
Barrel life, keep it cool and clean and I would think you should get 3k+.

Good luck!

Yep the Ackley improved is the one I would want.Either that or a custom built .22-250 with a tight chamber.

A 22 250 AI would be great I'v heard of guys using the standerd 22 250 for F class with the 80 and 90 gr Bergers. It would make a great long range coyote thumper

The 22-250AI is a cool cartridge. The folks at Shilen told me once, that you can't really over stabilize a bullet. However, a lesser bullet will come apart and turn to smoke out of this round. The rifle I had was a 1/12 twist and lesser bullets would not reach the hundred yard target. Better bullets will do fine, don't expect the lighter constructed bullets to perform. I agree with your opinion, that twist should work well for longer ranges and heavier bullets. It would be a lot of fun to shoot! I'll try and find the loads I used and post later...Good Luck, and let us know how it works out.

NIce, 3325fps with 80g amax is pretty impressive.

I've got mixed opinions on barrel life so far. Some say as low as 600, some as high as 3000. I would be happy with 1500-2000, I really dont know, but a couple guys that have them and bore scopes say they'd be surprised if it went 600-700. That is not very good and if thats the case, I think I"ll probly pass. I dont feel like a rebarrel every year. Really couldn't afford it.

What I dont get is this. I dont see how a regular 22-250 shooting 50-55's at 3600-3800 will still do 1/2" with 2000 rounds down them, while the 22-250 AI shooting the 75g at 3350 or so will cut back on barrel life as much as half?? Hows that work?? I've always thought the slower the pill, the more barrel life, the faster the pill less barrel life, or maybe I should say throat life. I cant see how the twist would make up that much difference in loss of life when your pushing a bigger/slower bullet. I realize there is a couple maybe few more grains being sent down that 224 hole, but I still dont see how it would be that drastic. Anybody know for sure??

I'll think about it a bit and see what happens.

Keep her clean and clean and she will last a long time!

Remmy,

The new 22 caliber 35 grain Ballistic Tip Lead-Free would be a screamer out of the 22-250 AI. :twisted:

Well bud I'm thinking about my next 22-250 being an improved one. It would be a great rifle for yote hunting. Have one guy with an Ar for the ones that get called in close, and have the 22-250 AI as the long ranger for the ones that don't come in or the ones that get away from the close range guy. I'm really liking the idea of a 75-80 gr. bullet smoking a yote at six hundred yards or so.

I've been told I clean my guns to much anyways so If I keep her clean I think barrel life could be at least 1500 rounds. I don't think a 22-250 AI is as extreame as your 300 RUM, or a 6-06 would be as far as barrel life goes.

If you get it and don't think it is going to work out you can always sell it and get something else. Just my thoughts.

 

[remingtonman_25_06]

Well I decided to pass on it.

I really dont need it with my 22-250 and 25-06 that I have already.

Would still be nice to have one day though...

how far would the bullet travel before it vaporized!!
