	The reason for multiple rim thicknesses on chambers is the various donor brass used in modern variations on the .44-77SBN chambers. So depending on what donor brass they planned to use there was quite a variance. Some of the newer brass wont get a firing pin strike hard enough to fire the cartridge, and headspace can be quite an issue in older original chambers.

	The old 3-1/4 .44 Bell basic and the Huntington HDS I thing that was Bell with their head stamp. Those rim thicknesses ran .078-.082". I still use that brass for the .44-77's and the .44-90 BN's. But the Jamison brass was a Gods send when they made it for both calibers. With those two calibers being a bottle neck a thinner rim thickness is not much of a problem because the shoulder will hold the head space if you don't run the shell through the sizing die. Even with the Shiloh's .44-2.5/8 bn shallow 11º shoulder.
