I traded in to a nice looking nickel plated 94 a few months ago and didn't really know what I was getting. The fellow said he never shot it. Upon getting it home and checking it out it seems to be a bit of a Frankenstein rifle, the receiver is a nickel plated Oliver F. Winchester commemorative that was originally gold in color I think and chambered in 38-55? At some point someone has put an octagonal barrel in 30-30 on this action. From what I've read the 38-55 action should load and chamber 30-30 effectively, but the issue I'm having is that the action won't close all the way on a chambered round. It has no issue closing without a round in the chamber, it's as if there isn't enough headspace? Any help would be great, thanks!
