It took two shots. First shot was barely over its back. That was my fault. The deer moved 30 yards between ranging and the first shot. I didn't realize this and told her to take the shot. After the miss, the deer stayed in the same general area. Taking her time, she re-ranged it, re-dialed it, and calmly pulled the trigger. The bullet hit EXACTLY where she was aiming. The deer fell over backwards and instantly went to deer heaven.
It's funny because she's kind of a jokester and no one believes her on the distance.
She used a Tikka T3 lite 270 wsm, Hornady 150 grain SST's, a Bushnell yardage pro laser rangefinding scope, Harris long bipod with my backpack as the rear rest. She's not quite 5 feet and weighs right around 100lbs. The recoil didn't bother her a bit. She now calls herself the best assassin in the Jr. Sniper League.
Thanks everyone. We learned all we know about long range shooting on this site.
