[QUOTE="codyadams, post: 1975454, member: 87243"] Update! Today I took my coworker and his young son out for his first ever big game animal, a doe pronghorn with my Norma. We spotted a good sized herd out in a field we often hunt, and got on top of the farmers hay stack to set up for the shot. The wind was 10 to 25 mph at any given moment, but averaging around 15-18 sustained, moving from a strait on 12 o'clock wind to a 1 o'clock wind. I ranged the group from 650 to 690 yards. While waiting for a doe to present us with a good shot and the herd buck to stop pushing the does around, I had my buddy practice aquiring a target and doing dry fires. About 10 minutes later, once the herd buck stopped pushing them around long enough for us to get a good range, a good wind call and get a doe singled out and 100% identified that the shooter and myself, the spotter, were on the same one, I had him get ready for the shot, and we all put on ear pro. She was facing to the left. I confirmed dope, it was 12.5 MOA up and .5 MOA right, 661 yards and a 16-18 mph wind coming from about 12:30. I told him to go strait up the off side leg, as she was slightly quartered away, and squeeze slow. Shortly after, I heard the report of my rifle, and slightly over three quarters of a second later, I saw the rear end of the doe drop hard with the impact, then a dust cloud come up behind the doe from the bullet passing through, and she made a mad dash. I zoomed out of my spotting scope and watched as she ran flat out for about 10 seconds, then began to slow down, and after another 5 seconds, she tumbled over.
