Uh-oh - you forgot to mention Chris K's fav Lee-Enfield... so standardized that parts are interchangable without armory-level gunsmithing. And Mosen-Nagent, and Arisaka, and... the list goes on. Just about anything from the M93 variants on up to the most recent "modern" bolt guns works for me.

I confess to really liking most anything with a big claw extractor... but most of the others work admirably, too. Although, now that I think about it - the first service rifle issued to me was an M14, and they were annoyingly prone to sending the extractor assembly whipping off the bolt and away into the weeds... much as I love that rifle (and the M1A version).
