i personally have never seen an entry or exit wound that big. i have used both a 25-06 and a 300 wsm calibers both bigger and smaller than the 7mm. the closest i ever came to a whole that big was when i shot a doe in the chest at 3 yards. the entry whole was about 3 inches (she was laying on the ground i had shot her in the chest already but she was still alive, don't believe in letting an animal suffer to death.) i am not saying that that picture is not real. but at 100 yards that is an awful lot of damage!!
