Did the ever open on the first deer. Second deer sounds like you hit too low, or the bullet penciled thruSmall sample. 2 mature bucks. 1st one shot directly middle of the shoulder. Took off like nothing happened. Made it about 150 yards and was not slowing down and I made a lucky shot and hit him in the head.
2nd one shot little below mid shoulder. I was watching in binos and saw the red. Never found it.
I shot 7/08 for years and definately not used to that.
