here is the exit hole from my 25-06. I shoot 85 grain hornady ballistic tips. This fine lady was about 300 yds out when i poked her.
The front one in this pic was also shot with my 25-06. He is getting tanned at the moment but I shot him while he was quartered to me thru the neck and out by the ribs. The taxidermist told me that the exit was the same size as the entrance and missed any large bones.
From what I have found with about any rifle. The distruction happens when the bullet hits a thick bone. Same goes for a 25-06.
