Mine is an old, pre-SN M512 Sportmaster. Occasionally a cartridge will not rise high enough to be taken into battery by the bolt face. I suspect it needs to be taken apart and given a good cleaning.
Where can I find disassembly instructions?

There are several good books on assembly/disassembly. A used book store or a book table at a gun show will probably have one. The Gun Digest rimfire book does not include the 500 series for some reason, but the NRA Firearms Assembly 3 does.
Thanks for the reply.
I have the NRA manuals, old ones though. The shoulder arms manual includes the M514, but this is a single shot with a bolt-head safety, quite different from the 512.
