I should have included the 6.5-06 in the chamberings I was looking at! :) My concern with the 6.5-06 is that we have another 25-06 rifle, used by other family members when we hunt, and I was concerned about my wife and/or kids getting ammo mixed up. It "shouldn't" chamber, but they really aren't that far off. Do you think A 6.5-06 could close on a 25-06 chamber?
