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

I did try a 22-284, It was the worst wildcat that I ever experimented with. barrel life without cutting off and re-chambering was only a few hundred rounds and I could never get the velocity that I expected................not to mention bullet blow-up's.

Switched to 22-250AI and have been happy ever since. there are times when too much is way too much of a good thing, that's what the 22-284 is

I recall speaking with Kevin Wyatt over here in Medford... he had built a 22/284 for customer who was a relocated Texan to here in Oregon....When the customer picked up the gun, Kevin told him that the life span of the barrel was going to be about 250 to 300 rounds or real accuracy... and at about 500 rounds the accuracy was going to be gone.... that at that point, it needed to have the barrel set back and re chambered, or just needed to be replaced....

Price of the barrel work was $500. When Kevin told him the above, the customer quickly plunked down $1000 and told him to start working on two more barrels....for the same action...

Some guys like corvettes - some guys like chivettes

I thought your .220 Swift was a pretty Skookum coyote rifle?

Anybody think a 65 gr Sierra game king would work in a 10 twist. 22 creedmore?
I'm thinking it would be pretty good for coyotes in my neck of the woods. 500 yards and under with maybe a 250 yard zero. Just thinking out loud but the 22 creed is definitely moving the needle for me....

I had a straight 22-250 with a 10 twist barrel, It shot 65 SGK well. But if I was building another I’d go 8 twist, which should also shoot 65s just fine, and then some

Well I can buy that a 22 Creed is an updated 22-250....

These longer bullets and setting shoulders back with a good web under them so they run higher pressures is all good.

Think it would get a 65 sierra game king around 3800+fps?

YES, I have thousands of these bullets. it says right on the box 7"-10"twst bbls

YES, they are "pretty good for coyotes"

NO, not even in your dreams.

Only way you would get them to 3800+fps is if you had an out of whack Shooters Chrony (like most of them were). With a real chronograph you would never hit this mark

Cool....just asking.

I've got an 8 twist 22 250. shoots 88's pretty good. Out of curiosity what kind of velocities with 88's or 75's is a 22 Creedmoor getting?

It’s waaaay more worth shootin shiit brass and fire forming... 😂😂😂

Same/same...

According to my fuzzy math and spelling skills the Creedmoor case diameter should be:

.462 - (.025 x tan(30)) x 2 = .433

This is the Creedmoor diameter at 1.515" from the cartidge base

So the Creedmoor reamer should clean up a .22-250 chamber which measures .416" at the shoulder.

So now the question is if the benefit of the enhanced 30 degree shoulder is worth the effort if you have a .22-250 with a slower twist barrel.

Shoots great!

I am re-reading Alaska's Wolfman.Frank Glaser liked his 220 Swift for Wolves,sheep,caribou and moose. He didn't like it for griz but did kill a couple with it. Like with Scenarshooter it is more about the hunter/shooter than the tools. I am thinking that a really light rifle w/ a suppressor and a SS 3-9 hd scope would be perfect in 22 creed.

YMMV

UncleA : Thanks for your Trig-Analysis , pretty much matches my results.
As for your question about the benefit of a slow-twist 22 CM , that project is on pause for now, ha
