I have an old Ruger M77R in 300WM. Although it is my favorite hunting rifle and comes in at close to 10 lb., you might consider the Mod 70 over the Ruger. I do have a pre 64 in .270 and it is a nice rifle. It is one of the rifles from my grandfathers legacy. Metal strength is a non issue as stated in one of the earlier posts!
No such thing as a stupid question. What is stupid is not asking it.
