Im wanting to build a long range rifle in 300 rum.
Can any Savage long action work for this like maybe a 30-06 action? If not which actions will work? Ill be on the look out for some 300rum savage rifles for sale for a donor.
I would prefer a repeater but if its too much of a problem to do then a single shot is ok. Should I just start with a new target action?
Can someone please lay out the best way of doing this?

Oh and if anyone asks why I want to do this in 300rum, my answer is because I want to :)
