So at this point, after reading all the helpful info and advice y'all have shared, I'm pretty much down to the trusty ol' 30-06 or 7mm Rem Mag. While I think both calibers would be more than adequate for my purposes, here's how I perceive the advantages of each relative to the other:
30-06 advantages: ammo more readily available, slightly cheaper ammo, widest variety of quality manufactured ammo, less recoil, more versatile, nostalgia (won two World Wars, same caliber my old man shoots)
7mm Rem Mag advantages: higher BC, more ft. lbs. of energy at longer ranges, flatter shooting, better for long-range target shooting (if I ever get into that)
Am I missing anything there?
The real deciding factor might just be availability... I have my heart set on the Weatherby Vanguard Weatherguard Bronze model (soooo sexy--linked
HERE), but I can't find one anywhere in either caliber, and Weatherby is way behind on production due to issues with getting barrels from Japan. If I find that model in either caliber, I'm most likely going to pull the trigger on the spot (excuse the pun).
Can't thank you guys enough for all the helpful information!!
