22-250 AI or Creed and 7 or 8 twist?

[RiverOtter]

I'm sure there's more than a few here with intel to steer me straight. Haha.

700 BDL SA is my starting point and 88 ELD's is my destination.....for reference.

 

[Lineman]

I went with 7, but either should work fine from what I’ve seen.

R26 and 88s are all I’ve ever shot.

 

[Oatmealsavage82]

Id roll creed only as it is the easy button. Especially now that its a sammi cartridge. 7 twist, 88s in Alpha brass should work wonders......

 

[RiverOtter]

Kinda what I thought I'd get for responses. Haha.
I'm sitting on a chunk of vanilla '250 brass, hence the 22 Creed hesitation, but that's hardly a deal breaker. Smith has the 22 Creed on hand, so there's that as well.

As per the 7 twist, is spinning jackets off hummingbird weight 22 boolits a thing?
88's are obviously gonna be the staple, just curious to know what to expect if I step outside that realm.

Appreciate the input gents.

 

[Dan In Alaska]

I had a .22-250AI with an 8-twist, before the 88 was offered.

I now have an 8-twist 22 CM, and it does not seem to spin the 88s fast enough to consistently make round holes at 100yds.

If you want to shoot 88s, twist faster than 1-8".

 

[Oatmealsavage82]

Pretty sure you could fire form that 250 brass to the creed chamber if you were so inclined

 

[RiverOtter]

Wow, I guess that answers the 7 or 8 debacle...
Thanks for the thousand words, Dan.

It definitely matters a bunch more to me that 88's fly than 55's.

 

[RiverOtter]

Pretty sure you could fire form that 250 brass to the creed chamber if you were so inclined

That'll be icing. I really only took a cursory glance at the Creed, but it's arse looked so rebated that I assumed it was some weird dimension. I'll definitely look into the possibility of burping brass for sure.

 

[Dude270]

I've had multiples of both chamberings, no way I wouldn't do the 22 creed now. No fireforming is nice. You could form your '250 brass in a creed.

I have had two 8 twists that handle 88s but I see no reason not to go 7.5 or 7 twist.

 

[Horse1]

The next round of projectile R&D is unlikely to require LESS twist. 1:7 is a no-brainer in either vessel IMO. Quickload claims '250AI is 47gn capacity and 22Creed is 50gn.

 

[raghornjp]

22 CM in a 7T is the way to go
My experience mirrors Dans when trying 8T and 88’s

 

[Big Stick]

I have Speedmires in 7",7.5" and 8" RPM and all of mine LOVE 88's,for a total of (5) different rifles. TRUE RPM will certainly effect things,as stabilization is a function of twist rate and in conjunction with lineal velocity,to factor gross RPM. I measured my 8's and they are as billed.

Now as money in the Bank goes,Reserve RPM is your friend,within reason. 7.5" gets you 90gr Beer Can stabilization,as does the 7". Atmospherics also effect flight/stabilization. I've shot a Jaziilion 50V-Max at Warp Speed,in multiple 7" twists,in various .473" based chamberings. Never an issue,even in 22CHeetah(at 1-14").

I shoot multiple 22-250's,though none faster than 7". Same goes 22-250AI's. Go Speedmire and never look back. It is zero bullshit excellence and Alpha brass is simply fucking amazing. Sell/trade the 22-250 brass and cut to the chase.

A 700 is an easy way to fly and you've the inherent COAL latitude,to do it all,without getting cute. The Speedmire is simply a 22-250AI fully formed,in over the counter brass. 88's crowding 3300fps,are a Modern Marvel.

Nice to see both it and the 22 ARC get unveiled. Hornady is simply on fire and making SMART moves,which is rather refreshing in The Industry................

 

[RiverOtter]

Tonnes of good feedback, as per always....

Much obliged!

 

[Big Stick]

There's multiple Teeker 1-8" 22-250's in the neighborhood,that are slinging 88's expressly. Forgot about the one I punched Speedmire and it of course does too,but The 'Los fucked me out of it...........

 

[RiverOtter]

Small primer pocket? Is there an advantage there in a CM hull?

I notice the 6 Five Creed has both options available, so what's up with that and what route is best?

 

[RiverOtter]

Also, went hunting for Alpha brass and ran into nothing but 'Out of Stock'. Found a source for 22 CM in Peterson, but know nothing of the brand. Any Peterson users here care to comment?

 

[raghornjp]

Hold out for alpha

 

[Calvin]

bluecollarreloading had alpha a few days ago.

Alpha 22 Creedmoor Brass LRP with OCD Technology · Blue Collar Reloading

 

[RiverOtter]

Appreciate your effort, Calvin, but brass is deemed an 'explosive container' and is on the naughty list of things the US won't ship to Canada. It's actually an export restriction, not an import, but our wonderful 'leader' post 9-11 requested that we be added to the list with the other Arab countries that are deemed off limits to US firearms related goods.

 

[RiverOtter]

Will likely end up gunning Peterson brass while I await Alpha stock up here.

On another note, what barrel length is everyone gunning on their 22 Creeds? 22 or a smidge longer to garner velocity gains.
Obviously cut to balance is ideal, but that's dictated by platform.

 

[Wiserfool]

I think Gary Easton at Bighorn Sales has Alpha and Peterson 22 Creed in stock.

 

[raghornjp]

You can get all the speed you need out of 22”
I’m getting 3484 or so with a hot load of 22 in alpha brass with 75’s

 

[Oatmealsavage82]

Talk to Gary at bighorn sales for alpha brass.

 

[RiverOtter]

I think Gary Easton at Bighorn Sales has Alpha and Peterson 22 Creed in stock.

Hey Wiser, much appreciate the heads up. The Bighorn site isn't up and running yet, so I couldn't find them when I searched the Canadian Alpha distributors.
Got a couple hundred pieces inbound.

Thanks again!

 

[Big Stick]

Speedmire 88's,are just plum amazing..............

 

[RiverOtter]

Got a half k in the larder for barrel break in....
Platform is getting cut around same.

 

[Big Stick]

I've been flogging on an OEM Montucky 243 Win this pass and will get it headed South,to become a 7" RPM Speedmire at 21.3". Dupe/dupe.








Mainly,because I like round numbers.................(grin)

 

[standeford]

I had a 243 Win Montana rebarreled to 22 Creedmore a while back. Went with a 7" because even though an 8" would have been fine for the bullets I planned to shoot, I figured they'd keep making better ones that would be longer rather than shorter.

That and I have never had anything twisted too fast. I don't shoot Sierras so spinning something apart is not likely to happen.

 

[Big Stick]

Got Pearl Harbored yesterday,with a Montucky 7" RPM Lilja Speedmire.

I reckon I'll keep hating on the Montucky 243Win................(grin)

 

[Horse1]

What bbl make on the 243 to make it .224Creed? I've Lilja'd the last 3 'cause it's easy-button on duping the taper. Need 2 more 1:7 .224's, first to become a 223, 2nd I'm back and forth between 22Creed and another 22-250.

 

[Big Stick]

I've had rather good luck with Lilja,for many moons.

When the mood strikes,I simply source a barrel setting on the shelf,in the RPM I want. Most everything I do,gets recontoured from there.

You want a Speedmire,fuck the 22-250.............

 

[Rolltide]

Has anyone messed with the 22 ARC yet?
