Home Forums Hunting & Shooting Ask The Gunwriters 22-250 AI vs 22 Creedmoor

A 22 Creedmore is more likely to gain "domestication"....

Second hand from George Gardner of GAP (via Pat here as mentioned), a 22 Creed reamer is all that’s needed to update the 22-250.

Creedmoor is 0.028" shorter to the shoulder juncture. Does that matter? Almost like the Creedmoor was designed for the Ackley crush fit of 0.04" or there abouts. But it does enplane why it is perfectly fine to fire form 22-250 in a Creedmoor chamber. Also "splains" why all of them do well with the 1 in 8 twist and 75 to 80 grain bullets.

Should be the same on deer...

I am thinking the 90 and up are better in 6mm but I don't want to limit myself arbitrarily. Will a 7.7" twist handle these or should I go faster? I shoot mostly at lower elevations 500-2000 feet. My previous experience with SMKs in other calibers mostly 7mm was they are not a game bullet by my recktomning.

up

OK I will bite. Is the Creed good to go for 90's+ or is a larger case called for? The 75 grainer seems to me as an optimal match.

Larger case?

Guys shoot 90's in .223's for what that's worth.

Bringing an old thread back from the dead rather than starting a completely new one about the 22 Creedmoor. I'm curious if any of y'all that have built one for the fast twist heavies and how they've performed for you. I've got a Model 7 I'd like to run a switch barrel setup with and that Creedmoor is screaming my name for a sweet shooting predator/varmint rifle.
How do the 95gr Sierra MKs do on coyotes? Bobcats?
I'm also considering loading the 83gr Hammer Hunters (same length as MK) for chasing lions. This bullet requires a 7'' twist.
Seems like this would be a whole lot cheaper than shooting my magnums for fun and hopefully won't tear up the pelts too bad either.

A creedmoor reamer will clean up a x 47 chamber, but to clean up the throat it would prolly have to be set back.

I’ve not used the 95 in .224 but have used a fair few SMKs on foxes, goats and the odd pig. The light ones certainly work fine on foxes etc and the heavier ones (eg 107g in 6mm or the 155g in .308) work just fine on pigs as long as they aren’t being launched too fast.
I wouldn’t hesitate to try a 95g .224 SMK on a pig. It’s the best way to find out!

Why a 22 CM when one can have a 22-6MM Rem.AI with a 1/7 twist?

Barrel life is the main reason for me, not that good in the Creedmoor and pretty lousy in the 22x6mm from what I have heard but this is with the 75-85 grain bullets so don't know what the heavier bullets will do. The heavies might be even worse depending on how hard you pushed them. One of my gunsmiths has done several 22 TTHs and he has done a couple that are on their third barrel.

The biggest reason I'd choose CM over Rem AI is because of my limited mag length in the Model 7 action. It's a bit shorter than the Model 700 SA.
CM has readily available brass from Alpha Munitions.
No fireforming = longer barrel life on a cartridge that's already going to be short-lived.

So I guess I'd ask in return, why 22-6mm AI when you can pick up high quality brass that's ready to load and shoot immediately?

Just because I want to.

Touche

I thought that the Remington Seven and 700 SA used the same magazine box, follower, and follower spring.

That's correct, but you can get the modified, longer box option, from Wyatt and that will not work in the Seven because the trigger resides there.

i kinda always wanted to build a 22-284 just never did ? but if i did i would call it Rockie from the movie ?????

I had a 22-243_AI set back and ran a 22 creed reamer in it then cut it to 23" its a keeper.... running 75 grain vmaxes at 3250 really easy using Hornadys 6mm creed brass ran thru a Redding bushing die. Easy peasy
