Real world velocity gain if comparing same/similar set up? 75gr bullet at same pressure out of the same barrel.

It’s gotta be a 100 or better if not more. I think it kinda allows you to step down to a slower powder with the extra case space but I’ll be watching to see what others get. I’ve got that 1-7 Hawk Hill ready to rip. Kinda wanna strap it to a Montana though.

Hornady load data shows 3350 as max for 75s in the 22-250. Superperformance. That’s with a 24” barrel.

You could probably do same with a 20” barrel in the 22 Creed.

I've read of measured case capacities being about 45gr vs 52gr. That's about a 15% bump, which should indicate around a 4% velocity bump if pressure is held constant. Using a 3200fps MV, that should point to something like a 130fps gain for the Creedmoor, or at least something in that ballpark. I've also read reports from shooters that saw 100-150fps difference when owning both chamberings.

Some, but the twist is what really matters, assuming there are actually any .22 CM factory guns available. There are gazillions of .22/250s, past and present, if you can live with the standard rate of spin, which Eastern varmint hunters probably can.

Then there's the question of ammunition. While many or most here are handloaders, that’s not the case overall, and it’s a real concern for some.

I've owned a 3 fast twist 22-250s,you can figure on 3150 fps, give or take with a 22" barrel and a 75.

The same powders and bullets have given me 3350-3400fps in 2 22-250 AIs and 2 22 creedmoors. The 22-250 AIs were 22" barrels and the 22 creedmoors were 20" and shot surpressed

Pretty sure you could stand on the creedmoor a bit more but I don't see the need.

One of those would probably be the smart choice for Joe Average, if it can be found. If he ever starts handloading, the barrel would be ready for long ones.

I’m talking hand loading with a 1-7” barrel of same length. Could care lesss about factory ammo availability.

Are you thinking about buying a factory rifle, or are you going to have one built? There's no doubt the creed kicks the 22-250's azz. Don't get any more simpler than that. You are wanting to shoot 75's from what I gather. As you should know, the 22-250 with a 1 in 8" twist (as in the Tikka with that twist rate), can stabilize up to an 88gr bullet. How many factory rifles are chambered for the 22Creed? How easy do you want to make it on yourself?

I've done lots of each,including punching out in progression,upon the same spout and would factor 200fps. Hint.

88's are where it's at. 21" dupe in 7" RPM here,with same. Hint.

Rebarrel on a push feed 70 in a McMillan FWT pattern.
Brass and dies in hand was my only real motivation to go .22-250, but the juice sounds like it’s worth the squeeze

Lets see it when it’s done.

In a Ruger rebarreled to a 22.250 with a one in 7 twist. With 80 grain bullets ( and 75s also ), using RL 15, it gives me consistent and accurate, 3350 fps MV. 4064 will give me 3300 fps.

No pressure issues and a batch or two of brass has seen 20 plus reloads now.

^^^^^ THIS ^^^^^

If you're actually getting significantly higher velocities than those easily calculated via Mule Deer's 4-1 ratio rule of thumb, you can be sure that you're also getting that performance bump through significantly higher operating pressures.
