.22 Creedmoor Shooters

[rob221]

I've got a Brux 1:8 twist at 24 inches and couldn't be happier with it. I've been doing load development primarily with Hornady 88 grain ELDs and H4831sc. using Alpha brass, Whidden sizer and a Forster .22-250 Ultra micrometer seater that had a .22 Creedmoor reamer run into it to recut the shoulder. Everything is working great.

What velocities are you getting?

An 8 twist will serve you well in that bigger .224 case round. Even moving the 90s although I think you'll be happier with the 75/80 weight class bullets. You'll get around 3500+ fps with both and you won't think about the 90s when you see what the 80s can do Waaaay out there. Good luck.

My cojones aren’t big enough for those loads

What's them things got to do with it? I'm shooting 80 gr Nosler CC at 3511 fps out of a 28" barrel. I have 200 new cases to shoot so I haven't reloaded any or checked primer pockets. However, to the eye, there are no shiny spots on the case head and primers look fine. Bolt lift is also normal.

That's zipping right along, what powder are you using to get 3511 from an 80gr bullet in a 22 Creed ?

 

[nmkid]

H-4350. I don't like to run, "hot" and was more than surprised when the Magneto gave me 3511 fps as a ten-shot average. Also, that was fired in about 85* weather.

anyone necking down lapua brass? Curious on process. plan to use my 6mm creed dies with .251 bushing.... not sure if one step will work or if i'll have to partial size with .261 then go down to .251

I’ve been necking down in one pass for my 22-234ai. It takes a good outside neck chamfer and I still crush a neck on occasion. I’ve been thinking about getting another bushing and taking it in two steps.

update from me - lapua 6mm creedmoor brass, necking down in a single pass with .252 bushing, and i stole the tapered expander off my 223 dies. working well so far.

Damn good velocity with a 28" barrel. I'm getting roughly 3550 with 80s from my 22-250 AI thru a 30" barrel. Not a hot load but getting warm. Accuracy is excellent.

Has anyone really checked the case capacity of a 22-250 and the 22 Creed ? Is there really enough difference to not just stick to the old one ? Other than have a rifle that says Creedmoor ?

Too close to worry about it. Stepping up to the 22-243 or 22-284 would be the better option if a performance upgrade is desired.

That was my conclusion as well. I chose to go with 22-243ai.

 

[Browning442]

For what it's worth, i began using 22-250 AI load info from Quickload for the 22 Creed... case fill was 90% at best, and loads were very mild, low pressure, low velocity.

I have been using 22-243 load info for the 22 Creed and it gets me a lot closer to its potential. I'd say it's not as close to the 22-250 as you think. The listed capacity of a 22-250 is 44.6 grains, and 22 Creedmoor is 52.0.

So your 22 Creedmoor has more case capacity than a 6mm Creedmoor and is nearly the same as the, much larger, neck diameter 6.5 Creedmoor?

Actually what I saw was the listed capacity of the Ackley improved was about 48 vs 52. You can look at 4 different places for that fact and you'll come up with four different answers. Either way they're very close to close to really be concerned with.

 

[Browning442]

That was going off Primal Rights info. I checked the reamer print and it is listed at 50.28

Either way, quite a bit more than the standard 22-250.

I thought you meant standard 22-250.... no doubt the AI is quite a bit closer.
At that point it comes down to preference, fire forming vs. necking down

 

[B23]

Personally, I'd never bother with doing a 22-250AI over a 22 Creed. I think the 22-250AI and 22 CM are a lot closer in performance than many would like to imply, but the 22 CM is just so darn easy and is a straight neck down then load and go, unless you get your hands on some Alpha Munitions 22 CM brass, then you don't even have to neck it down.

There is nothing "magical" or my personal favorite, "it's more efficient" about any of these things and it still takes either more powder or higher pressures to push bullets to faster velocities and it's pretty difficult to achieve one without the other.

It's really not that big of a process actually. Just load 22-250 ammo and fire it in the Ackley chamber. Accuracy is top-notch while fire forming so it's pretty simple. Saves quite a bit of money also versus buying the 22 Creedmoor brass. But you're right it is a little bit easier to load and go.

 

[Browning442]

I've never fire formed honestly... doesn't sound too complex, I just like the idea of necking straight down. If i had a mondo pile of 22-250 brass... that might change my mind. But a one-step neck down from lapua 6 creed is as easy as it gets!

I have a 280 Ackley as well as a 6-284. They make factory brass for the ackley, and 6-284 is again a straight neck down from 284. I just prefer it versus fire forming!

Personally having necked down several cartridges to smaller necked siblings, I'd rather seat bullets in standard brass and fireform. Definitely less steps and only needing the 40° dies, makes the cost only a little more. Fireforming was intimidating at first not knowing what to expect. What I've learned is, I can still use the loaded rounds as my hunting( or target etc) rounds as they are just as accurate as if shot from fireformed brass. Also less brass wear (stretch) with the 40° shoulder. I guess that's what makes us all different. Too each their own I guess. I do have about 1000 pieces of 22-250 brass so that's a good reason to stick with the fireforming rather than change to the Creedmoor.
