I was thinking along these same lines, Art, and wondering if perhaps at longer distances the 30-06 and other smaller stuff might not be equally as effective in knocking the "snot" out of "big" bears, 'cause the resulting ground shrinkage one could achieve at longer distances might be just exactly what one might hope to spend their hard-earned thousands for the privilege of exacting.........or not! (Perhaps we might have some of these issues removed to another topic forum where we might contemplate "Judging bears at 1/2 mile; Should I halve the distance?")

Sometimes, the air you 'let in'matters less than the air you 'let out'.
