RE: 30-06 vs 308
If I was to own only 1 rifle, and shoot factory loads, it would be a 300 RUM. The new "Power Level" loads they have developed are pretty cool. Gives you alot of diversity. The power levels are 3 different stages
Power Level 1 = 30.06 ballistics (Deer,Elk)
Power Level 2 = 300 Win Mag (Elk, Moose)
Power Leve 3 = 300 Rem Ultra Mag (Stuff that wants to eat you! ie Big Bad Bears)
