Dead is dead, you cannot recall an arrow or a bullet....sure you may have been HAPPIER with a bigger buck but my point is it's done, be proud, chuckle , and move on, the deer deserves that!!! I shot the wrong antelope this last october but you know, oh well there is always next time, he tasted good and I will always rememeber to look at them closer when laying prone and waiting for them to crest a hill, I saw buck, went boom sat up and then "oh crap" him me.....oh well.....nice failure if you will IMHO!
