My father has a Mannlicher Schoener .270 1950. It is an excellent rifle except for the scope mount. It has a side mount that flips over, it has already costed us a deer. The mount is made by packmeyer. I have tried to seek out a mount that will not flip over however its not like looking at the weaver site where they list which rifle the the mounts are meant for. Its like you need to be a subject matter expert and already know exactly what you need prior to shoping. Can anyone offer any help.
