Case capacity difference .20PPC / .20-223 AI???

[Phil]

Does anyone know how close the .20PPC and .20-223 AI are in case capacity??????

Nope.


Ever figure out how much a 40° shoulder ( improved) 221 fireball case will hold?

I'd like to know also....

My .20-.223AI, I prefer 5X45AI, holds 32.5 grains of H2O at 1.760" case length. Can't help with the PPC but think it would be just slightly larger. Of course proper throating makes the capacity usable.

There is a nifty search tool on ammoguide.com and they have case volume for a whole bunch of cartridges.

223 AI: 31.3
20 PPC: 33.5

Many thanks for that resource. I have abt a K or so of 7.62x39 that may need squishing into a 20PPC AI.
