RE: 7MM Rem Mag
One thing that hasn't been mentioned, I owned a Ruger Mark II in 30-06 and now a Browning A-Bolt in 7mm Rem Mag. The 30-06 kicked more in my opinion than my 7mm. My dad took my 7mm elk hunting last fall and on the trip that rifle harvested 2 bulls with 1 shot each. I loaded up the then new Nosler 160gr AccuBonds for him at max load (can't remember the details off the top of my head). I also loaded the 160gr Triple Shock Barnes, and both shot equally well at 100 yards-350yards, he end up liking the Noslers better, so thats what he shot on his hunt.
