So I have a custom 6mm creedmoor coming back from the smith hopefully middle of next week. I’m thinking of maybe making this a switch barrel set up and getting them to spin up a fast twist 22 cal and make this one deadly coyote rifle! I’m leaning towards the 22 creedmoor as it now has factory brass, good velocity, no fire forming. What barrel twist and bullets are you guys shooting? How are you liking them for coyotes?
Talk to me about the 22 creedmoor

Personally I wouldn't go faster than an 8 twist. 75-80s do great from that size case at around 3400-3500 fps. Explosive on all critters and will perform on deer as well. Not from my personal experience but some guys I know use them on deer. I'm pushing 3550 with 80s from my 22-250 AI which is almost identical to the Creedmoor. You'll enjoy it. Could go 9 twist but may have troubles with the 80s. You can shoot the 90 SMKs with an 8 twist also.

You'd want to make sure you keep your ammo separate, because it would probably be fairly easy to mistake one for the other.
I've shot a lot of coyotes with a 22-6mm and 75gr Bergers using a 9tw but I have a new 22-243 Improved build going together and it's getting a 8tw to shoot the 80 grainers. The 22 CM is about equal to a 22-250AI or 220 Swift so you'll want at least a 9tw if you want to shoot the 70's and a 8tw if you want to shoot the 75's and heavier.

There have been some reports of folks blowing up 90s when going above 3200fps or so. Also a lot of folks pushing them harder than that without any troubles. Barrel life might be spectacularly short but it'll be a great time while it lasts!
Yes, 8 twist krieger , 69 tipped matchkings. Superformance powder = the shiznaz !
I get no cats and very very little fox. Like 1 every couple years tops! So it’s all coyotes for me. How did the fast twist 22 for you do on dogs. I wasn’t really expecting it to be too fur friendly, and have a 20 tac for that when pelts are all furred up, but looking for a switch barrel on my 6mm creed for a longer range 22 cal for yotes. Just looking to try something
Have you considered a 22 Dasher? It'll get you most all of the speed, maybe 100fps less with 10 grains less powder. It's a very efficient cartridge, and a reamer based on Norma Brass would require no real fireforming. Making 22 Dasher from 6br lapua is also easy: neck down to where the shoulder should be, load and shoot.

Any big 22 will be great for coyotes. They buck wind very well and shoot quite flat and work very well to extended yardages.
Bullet speed will determine how much fur you bust up.

My 22 Creedmoor is doing 3511 fps with 80 gr Nosler CC bullets. It shot the 80.5 Berger's with great accuracy also. Went with the Nosler's because of availability and price. It's an 1:11 finished at 28". The only thing I wish I had done is to get a brake put on it. Not because of the recoil but more to keep the rifle on spot to see hits on small animals. Does that make sense?

Errrrch! So you're shooting 80 grainers from a 28 inch 1-11 twist barrel chambered in 22 Creedmoor, and you're getting great accuracy?! I think there's something not quite right with this picture.
Not actually a cartridge I’ve looked into at all! Take a peak but really don’t want to be forming or making brass. I like head stamped brass. If I were I’d love to try something like a 22x47 lapua.
Agreed!!
22 CM, AKA 22-250AI?
or is that 22CM = 22XC = 22-250AI?
Pick the one you can get the best parent brass for, because they're all about the same.
"Everything old is new again!"
Wait until 'they' discover the 22-243AI Creedstead! or was that Middlemoor?
Or....the 220 Swiftmoor.
Or maybe the....................
Ain't modern marketing grand?

Alpha Munitions is a new-ish brass company and not only do they make very good brass but they make 22 Creedmoor head stamped brass, too.

Thank you. I was actually meaning for 22 dasher. I have alpha brass for the 6mm and it’s seems to be really nice. And while I was doing the build debating a switch barrel my first thought was 22-250ai until I noticed alpha producing 22 creed brass. Head stamped brass is something I prefer, then no fireforming is another so it just seemed like the better way to go.

I'm a big fan of the 22-250, for an off the shelf gun that has decent factory ammo, for those that may need it, the 22-250 IMO is one of the best varmint cartridges available. I also like things with "Improved" shoulder angles, but, ugh am I getting tired of having to fireform. So it's not that I think the 22 Creedmoor is anything special, but if a person can get top notch brass that is pretty much ready to go right out of the box, and is a ballistic twin to the 22-250AI, uh yeah, I'll pick the 22 Creedmoor over it every time.
BUT, if you're wanting to sling the 75+ grainers for a 22 caliber bore, IMO, the 22-243 Improved or 22-6mm or 22-284 is a little better choice because they have more horsepower to drive them.
Running an 80 grain bullet thru a 7.5 twist barrel at 3500 fps would churn up 336,000 rpm. Same bullet, same speed thru an 8 twist is 315,000 rpm. Not a huge difference but one that could be the difference of blown up bullets vs ones hitting the target. If your running the 90s, your velocity is less and RPMs would also be less. I personally think in a bigger .224 case like the 250 or Creedmoor, your best to stay 8/9 for 80s or less and a 7-7.5 for only 90s and up.
