Hi 243winxb,
Nice images, and mighty nice of you to take the time, thank you Sir!
( Inspired now, I went on to Gunbroker and looked at various Auctions for new, unprimed, .30-'06 Cartridge Cases, finding lots of 100. Figuring, I may as well seek new unfired ones, than have someone else's who knows used ones. )
If I am to use .30-'06 Cartridge cases, modified to suit, they would be used with the Full Moon Clips, just as .45 ACP would...and, I would have them be as long as .45 Colt cases, rather than shortening them to be as .45 ACP Cases.
Or, at least, that is how I have it in my mind, to do, if it is possible to do.
AND, I would bear in mind, that the Case volume will be a little less than .45 Colt, for respecting Loading Density considerations.
This would eliminate any Head Space issues, even if obviously occasioning a very small unsupported area.
There was no 'bulge' in the .45 Colt Case which did seperate...nor in any other of the Cases fired that day in New Service Snubby.
Of course, I do not know what pressure I was getting with 10 Grains of 'Unique', but if Lyman felt in the early 1950s, that it was alright enough for New Services, and, for 1st Generation Colt SAAs without any caviat, then I expect it is less than many .45 ACP Loadings, for which the Revolver was originally intended anyway...or, that people at the time considered it forgivable, anyway, and not a problem or worry.
If we had to guess, what would we guess, the pressure to have been with that Loading?
.45 Colt Cartridge...10 Grains of 'Unique'...230 Grain Lead Bullet seated to normal depth for the Cartidge.
14,000 lbs PSI maybe? 14,500? 15,000?
And, the normal range for .45 ACP being...? 21,000 ish?
The figures attributed to these Cartridges are not fresh in my head right now...
Edit:
Just 'googled' for some 'SAAMI' references, found 'em here -
