The .30-06 is THE best round EVER! Vermin to Moose. Large bears in a pinch. 55 gr Accellerators to 220 gr round nose. It is the caliber others are always compared to. If I could only have one rifle, it would be an "ought six". You can still find the adapters to safely shoot .308 also.
In life, strive to take the high road....It offers a better field of fire.
