Where there ever any attempts to make a pump action rifle? And if they where, why where they not successful compared to bolt actions?
Seems like the pump action is more suited to rapid shots (since you don't have to loose your grip on either your firing or support hand to cycle the action) and it only takes a simple linkage and cam setup to turn a bolt action into a pump action (essentially just a straight pull bolt action with a linkage to bring the handle up to the handguard).
And in regard to there being no popular pump action rifles in military service: Did militaries just consider that added complexity not worth the firing advantages, or are there other factors beyond that?
(EDIT) a better way to formulate the point i was curious about: "why are non self loading shotguns usually pump action, while rifles are usually bolt action?"
