The receiver opening on the "1893 Patent" rifle is 2 1/16". The factory people thought it was in 32-20 caliber and we generally accept that this is true. Too bad someone couldn't bring in a batch of various calibers of ammo and try them in the prototypes. The factory doesn't have a lot of info on the prototypes.
The receivers could be lengthened to accept longer cartridges. There is a photo of a 30-06 prototype on page 87 of my book. The factory label said it was the only high powered 99 ever built. Ron Coburn told me it was not possible to build a modified 99 action that would accept cartridges of higher pressure than the 308 class of ammo due to the four degree angle where the bolt mates to the rear of the receiver. There is a photo of a cutaway 99 receiver showing this angle on page 122 of my book.
