Missed a head on deer with my 300 Whisper Contender on a "gimme" shot of about 25 yards. Sitting with my back to a tree, a solid rest off my knees and all the time in the world. The deer ran off unharmed. I couldn't figure out how I could have possibly missed. About half way between me and where the deer had been standing I found a "hit" on the limb of a tiny sapling, which couldn't have been more than 6mm or so thick. The limb wasn't shot off, barely even hit enough to hang down, but it was enough to send the 125gr Ballistic Tip wide of it's mark.
It doesn't take much.
