I recently purchased a 91/30 and I am having bolt closing problems. The magazine seems to load correctly and all rounds strip from the magazine appropriately. However, the extractor does not engage the rounds as they are chambering. This results in the bolt refusing to close. If I reopen the bolt at this time, the cartridge does not extract (but it will easily drop out if the muzzle is raised). At this point, most of the threads I see recommend cleaning the chamber and checking headspace. This is where my situation differs from previous posts... If I manually lock a round under the extractor and into the bolt face, the action cycles normally (the bolt closes easily and extraction/ejection is positive). This would seem to rule out inadequate headspace and/or a dirty chamber. I would greatly appreciate any thoughts or ideas.
