The .30-06 with modern 165 - 180 gr bullets will cleanly kill anything from mice to moose, are you just wanting something different? I own and love the crap out of my 300 SAUM, but honestly, it nor the 300 WSM or Win. Mag don't offer much over the 30-06 trajectory-wise other than more kinetic energy, coolness, and more expensive brass. IMO, the next step in significant performance over the 06' is the 300 RUM or 30-378 Weatherby. If you want easy, get a 30-06, if you want a short mag, get the .300 WSM (much easier than SAUM or RCM), if you want a true .300 Mag, go with the .300 Win. Mag or 300 RUM), or H&H if you want extra cool points.
