"Like most problems in life, we'd like to think there's a single or at least primary culprit for "lost and wounded deer". Blaming the bullet is an easy way out. Not too hard on the shooter. I'd probably go with a top 3 reasons as:

1) lack of understanding
2) poor execution
3) poor shot selection"

Yep, there is the never ending search for the magic bullet that will turn a gut shot into a bang flop 100 percent of the time.

"How many of you believe high hits [which usually bled inside the body instead of out side ] cause some lost deer? Lee"

This is a fact. Followed uptwo wounded bucks this past season for folks who shot them too high. Fortunately, we recovered them both.
