The 57mm case is 2.2" long. The .30/30 is 51mm or 2".
"Got the rifle.
The bore is .363 and it appears that the case is slightly wider than a 30-30 base. Somewhat shorter than a 30-30 as well.
Any thoughts? I'm thinking that it is a 9.3r360 or something of that ilk. Gun is teriffic. If I can get the brass and slugs I may just keep it as is. So much for projects.

Now, if the groove diameter is .363", it is a tight 9.3. If the bore diameter is .363", it is likely a 9.5mm X ?, as the groove diameter will be around .375". Just a guess from what Tom said above, re: "shorter than a .30/30 as well".
