I am not ashamed to admit to having buck fever in my youth but I have shot numerous deer and I can rule out buck fever in this instance. Im pretty sure I did a poor job of sighting my rifle in to start and not checking zero when getting to Montana was dumb.
Two years ago a friend and I did a sneak on some nice muley hogs and go to about 150 yards from a real nice wall hanger. I told my partner to take it as he had a clear shot and I didnt.
Boom no Deer. I found out he had sighted in his rifle with one brand of ammo and was shooting a different brand at the deer. He was shooting over.
This was not my problem. I learned a valuable lesson.. I was in a hurry before the season and didnt get in enough shooting time and I didnt check zero the day before I went out hunting. I wish I could blame the rifle but no it was the shooter...
