Home Forums Hunting & Shooting Custom Rifles & Wildcats fast twist 22 cal cartridge questions

I'd go with the 22.250 route...

that is what I did, but my barrel is not a 1 in 8 twist... mine is a one in 7....

but it does good.. I also have a preference for the often not mentioned, 80 grain A Max which my rifles find more accurate than the 75 AMax...

My fast twist .22-250 groups 80 gr. VLD/Amax's slightly tighter than 75's.

I've got some 80gr Amaxes loaded up to try but have to wait until the stock gets back from StockDoc. Having an adjustable comb put on it. I guess I could put it back in the LVSF Stock just to see how they do...

The std. 22-250 is about the stretchingist POS ever devised to be fired in a bolt action.

Even Swift cases pale in the need for a trim.

No doubt Re: 22-250 with 75 A-Max in a 1-8". I trust mine to hit it EVERY time. Mickey Coleman did mine.

And the 223AI is a close 2nd with a 1-8" and 75 A-Max. Longrifles, Inc. did one of mine and IT&D did the other. Both are perfect. Now looking at a 3rd to be built on a Tac-30 action with Rock Rem factory sporter contour.

I've always thought the 223AI had the best return on investment for components of just about any cartridge I've ever shot and/or loaded for.
Brass is cheap and can be found just about anywhere. Heck, if I'm behind guys at the range with AR's, I pick up all their brass after they are gone and take it home. My 223's and 223AI's have never been picky about brass headstamp brands.
Bullets and powder are cheap and the 223 AI takes a fairly light load compared to the 22-250 for very close to the same results. On a long day of shooting the 22-250 at rock chucks or other vermin in the prone position I pay for it with a sore shoulder for a few days and I can't watch the bullet strike through the scope due to recoil. Neither of these is an issue with the 223 or 223 AI, in my experience. About the only rifle that was more fun to shoot was my .17 Rem until I shot out the barrel and it became my 223 AI.

I have gone away from wildcats with the exception of my 223AI for two reasons--it shoots Black Hills 52-gr match HP 223 factory ammo as accurately fire-forming as it does my new AI reloads, about .5 MOA at 300 yes.

In NW Iowa where I hunt coyotes primarily the countryside is reminiscent of a checkered tablecloth with one mile square sections which means fox and especially coyotes seeking the most security will be resting somewhere in the middle meaning less than a half mile a road. It's rare then that using the topography you can't close that to less than half or 400 yes at max and usually much less. The 223 AI works well then. Add a bunch of wind and the longer range and I prefer the 243 though a 22-250 would work as well.

But it's--the 223 AI -- not a 22-250 which is both good and not so good depending on your perspective.

My AI cases seem to last forever and a 50-gr Nos varmint BT at 3675 (10 twist, 22") seems really effective on coyotes to 300 yds. I don't knowingly stretch it much beyond that range.

Of the cartridges listed, an 8 twist 22-250 would get my vote....

I have a 223AI...and its cool. Mine is a slow twist gun, and while it slings the hell out of 50gr bullets, those run out of gas pretty quick.

I am currently having an 8 twist .22 Creedmoor spun up. The goal is to run 80s north of 3500fps.

I didn't know the 22-250 could get 3,500fps with an 80gr. bullet.




Dave

Yeah -

Good luck with that -

Me either WOW!

22 creedmoor is too funny. Just call it what it is. 22-250. And 3500??

Closer to 22-250AI.

22 Creed and 22-250 share a base parent case and bore diameter..thats where the similarity ends...

And yes, 80s at 3500+ are happening as we speak.

How many grains of what powder get you there?




Dave

Me? Currently zero grains of nothing, as mine is still at the plumber getting screwed together.

From the guys who have had guns built by the same guy, with the same reamer, 43ish grains of H4350 shoves a Berger 80 around 3525 out of a 24" tube. I should be a little slower, as mine will be a 22" barrel.

Wow. That's beating out the .223 WSSM. I suspect you could get 5,100fps with the .40 gr. stuff.




Dave

What very few reports I have seen of the really light stuff show them exploding before they reach the chrono. Of course, all the rifles built locally have been 7 and 8 twist guns. I suspect a slow twist gun would do some pretty wicked things....but I am not sure why.

Quick Load shows a 22-250AI (my QL doesn't have 22CM - case capacity should be nearly identical) w/ a 80grn Berger VLD seated out to 2.730" COAL (0.135" shank seating depth) and 43grns of H4350 as a heavily compressed load, yeilding 3.487fps w/ a 24" barrel.










@ 80k+ psi.......
