I launched a 140 grain ab from a 7mm08 last year on a doe mule deer at 203 yards roughly. Dropped like a bolt of lightning hit it. Walked over couldnt find a drop of blood. No visible entrance exit wound. I field dressed it. No damage to heart lungs. Was like wtf? Did i scare it to death.....found a perfect 7mm hole in the high shoulder which hit spinal cord and killed it. Saw a hole exit the opposite side. Acted like a fmj. This was my first kill with it and a 7mm08. It appesrs to be a sturdy bullet. Try it on elk this year.
