I have no particular opinion on this issue, but before I even get started some rules of the road. I know strong feelings are attached to anything to do with those seven little numbers appearing in the same sentence. Friendships ruined, marriages dissolved, people often come to blows. Please, no death threats, or threats of violence. No calling others wimpy or weak or pathetic or lacking in basic knowledge.
I'm neither here nor there on the issue of the 06 versus 270 just for the record. Some say tomato others say tomahto. Many say the two cartridges ballistically are about the same. They both can throw a moderately heavy hunk of lead down over yonder at around or just under 3000 feet per second. Both are used for game animals in North America such as deer, elk, and moose. The 270 also can be used for Richardsons ground squirrels and the 30 06 has shot it's share of grizzly bears.
The 30 06 does probably win the nostalgia contest having seen service in three or four of the major wars the US has been in over the past century most notably being the caliber for the M1 Garand The 270 also has it's place in history being considered as an alternative caliber for the Daisy Red Ryder
Choice between the two is more a matter of personal preference than performance. Just the other day my 8 year old girl who is a death to Richardsons ground squirrels said to me, "Daddy it's time I stepped up to the 06, that wimpy ol 270 is just inhumane as all get out when it wounds those little varmints leaving them to suffer". I didn't have the heart to suggest the recoil might be a bit much, I mean the 270 goes "plink" and the 06 goes "kaboom!". I understand that she wants something with some energy left when it reaches the next county but I know she's not ready for that much gun.
What about you? Have a preference? For me, six of one, half a dozen of another. Some cows got horns, others don't.
