Never had to take a head shot at a deer, dad had to on a cow elk. at 220 yds 2 inches low, shattered jaw I had to chase for 7 1/2 hours while it choked on its own blood. Meanwhile mine was on the ground 10 yds from where the bullet hit. Elk are more durable but that said mine did not taste near as gamey as his. No one can sit here and say they will put every shot in a 1 1/2 grouping every time. Not saying I wouldn't just realize the outcome if it doesn't work and be willing to accept outcome. Pops and I had a little talk following that incident, so we'll see what he does next time.
