I guess i should've checked there as i do have ql
My 22-250 AI has more capacity than 22 Creed. Creed may be slightly higher than regular 22-250.

I agree 100% with @Mike D Texas
When I was playing around with the 22CM to build in January, I CC'd several cases given to me, in every case, the 22-250AI held slightly more than the CM cases. I had Lapua, R-P, Winchester (ww-super & WIN headstamp) those 2 headstamps differ, Sako and PPU for reformed 22-250AI brass.
For 22CM, I had Hornady (of course) and Alpha, which I had to return to my buddy. The Hornady brass was woeful for volume variance, I don't know what batches they came from, but, if that's what's supplied in factory ammo, then I'm glad I don't touch it.
Cheers.
P.S.
Doesn't look like I will be building anything, these new gun laws are RIDICULOUS!

on paper it seemed like it possibly would, but i wasn't for sure. that also depended on brass manufacturer.
The AI will always have more capacity than the creed. You can see the difference in case dimensions in the AI case vs the creed case in the first picture in my group.
Exactly! Also, there might be a difference in actual chamber. If these are factors, "I" measure them myself.
ADDED:
I only use H2O measurements to determine capacity gains on my wildcats.

I quit messing with H20 capacity of cases and just default to the standard practice of dropping powder charges a bit and work up. Some brass primer pockets & webs are stronger than others and makes the case capacity weighing a moot point. Alpha & Peterson brass, for example. Have less capacity, but handle higher pressures better than softer brass.
