Thread: Uncommon knowledge

Does anybody have some fun facts/uncommon knowledge they could share with me about two things:
1. The 30-06 calibre
2. The sako L61R, earlier 60s versions (bofors stamped barrel)

I have done a lot of research already, read through all the pages like Wikipedia, sako forums etc. Seems exact info on old Sako models is quite vague! I am keen for interesting things to learn about my new rifle
Maybe it's a silly question, I'm not sure.
