In Oct 2005 I put the .25-06 bullet through the buck's ear and out the opposite side eye. Virtually no external signs of a hit at all, and needless to say the buck dropped dead instantly. I expected a big exit wound and a shattered skull, but that was not the case. Bullet was a 100 gr Barnes TSX @ 3340 fps mv, range was just over 100 yards.
I can't go around recommending the shot, because it's an easy one to blow - resulting in either a miss, a dinged up antler or worst of all, a terribly wounded deer that will likely get away to die slowly. Still, it works like lightning...
Very weird though when the carcasses are all hanging in the barn and there's not a bullet hole anywhere to be found in one of 'em...
Never saw this post before, oh wait um...I wasn't here yet

Any how I guess it was 20+ years ago, my dad had a cow tag in the Toutle, so I went with him to help pack. He got on some fresh tracks and took off after them. I waited at the truck, about an hour later I hear a shot then nothing, so figure hey the old man knocked one down

so I grab my knife and head off towards where the shot came from. When I get up in there I found my dad sitting on a log looking over a dead yearling cow. Absolutely no blood entry/exit hole, nothing. I ask the ol man "where did you shoot her?". He says" right in the ear." The bullet had gone cleanly in one ear and exitted straight out the other ear. Stuck my finger in the ear and sure enough finger found a hole and came out bloody. Of course when I grabbed the head the whole skull was mush in the back, but it never broke the skin.
