Re: Factory long range rifle help!
You should have a very capable set up there! I shoot a Savage model 12 270 WSM for my LR hunting for all the species you listed and it works very well. But, I really think it takes reloading to really unlock the potential of the 270 WSM. HSM loads LR hunting rounds loaded with 150 Bergers that might be a good direction to look at.
Make sure to get some pics up when you get your rig and welcome to LongRangeHunting!!
