RE: Ruger M77
Whatcha gonna use it for Smitty? If deer or pronghorn is the only thing on the agenda, your 308 will do just fine. After all, it' s a 1000 yard sniper round. But if you want to hunt elk and larger game, I' d go with one of the 300 magnums out there. Either the Win Mag or the WSM. I don' t think the RUM is all that great a round and it' s expensive.
The Ruger is a fine weapon, but their trigger' s need some serious attention. If it were me, I' d look into a Tikka in 300 WSM or 300 Win Mag.
