7mm-08 AI capacity

[Fuj']

Looking for a specific water capacity for the 7mm-08 AI......
I have most numbers I need for my projects, but the AI number
has eluded me. Checking around the various forums have drawn
me a blank. I do have most cases in my collection to weigh things
up but can't find my sample AI case. Checking a factory not fired
Hornady 7mm/08 I have measured 55.84 grs water......I have a
wildcat in the forming process (not the 7mm/08 case) and need
numbers to back up the project.

Thanks ahead of time.....

56.3gr I'm pretty sure

56.3gr I'm pretty sure

That looks a little too close to the 55.84 I'm getting with
a standard case. That's only a .46 spread !!

Depending on brand of brass the 7-08 will be 52-55 gr. The 08 case will gain 3-4% going to ai. So you'd be looking at 58gr. Volume is not the greatest benefit to going Ackley, no case stretch is the benefit

Never said anything about going Ackley, and I do not do the Ackley's.
I'm working on new ground and just need a "documented" H2O capacity
number of the 7mm-08 AI for research and comparison. If you have 10
different numbers from 10 different cases, so be it.

There are some guys on Accurate Shooter/6BR that bounce these questions and answers around pretty regular over there. Lots of smiths, manufacturers, experimenters and wildcatters. Your question might be right up their alley.
