Hornady InterLock 165 Grain Spire Point with 55 grains of IMR 4350 has been my go-to load for 30.06 for 40 years. Out of my rifle I consistantly shoot .5" or smaller groups at 100 yards with it.
Check out the One80 headlamp http://www.one80light.com/. Once I got one of these I gave all my other ones away, and I keep buying more of these for presents for family and friends. Most useable light I've ever used in the woods.
