My take? Jack O'Conner singlehandedly "made" the .270 what it became with his prolific writing and abundant praise.
If there is one thing that the 270 would not be my choice in would be a brown bear encounter (assuming you actually were fast enough to do something about it)
In that case a 30-06 with a 220 gr would be my choice
Let me put it a little different than what you've read so far from other commentators.Is it a round that has come and gone or do you think it still has a future?
