Ask Jonathan about 2 friends he took hunting in NM to help them with deer. Same thing....saw deer and they froze...they had that deer in the headlights look on their face...he was pissed....forgot everything he just told them.
Over the years Stan I have shot a dozen bulls and one cow buffalo (she was the hardest to keep down). The ranch owner gave me a deal on her to remove a "trouble maker" - the cow not me. She had tore up more equipment than one would believe, sides out of stock trailers to fenders on tractors and a number of pasture gates.
Have shot that many more (dozen) for guys that couldn't keep their animal on the ground (poor shot placements). You can talk until your blue in the face about how to get close (safely) and where to put that shot. Then when it's time to go after their animal on the 23 sections of ground (no fences on property other than a few for different pastures) they seem to go "blank" on what we had just gone over. Had an old friend make a good shot and nothing happened, told him to reload then noticed he was using a small measurer for his powder. "How much powder are you using Darrell", "my target load" - .65 grain of 2FF. !@#$%^ He's shooting a .54 cal. T/C - crap that's bouncing off the thick hair of the animal. "Double charge your rifle", he didn't and same results, his wife sets up and tells me to kill the bull which was done within a minute.
Lot's of old war stories when still hunting in Wallace KS with the property owner on different hunts over the years.
