I disagree, a pass through is wasted energy.
Missing the mark is wasted energy, sir. You can cripple a ground hog with a shotgun and slugs if you try hard enough.
I've hunted groundhogs since about 1965 in half a dozen different states. I've used multiple AGs, .22LR, 22 K-Hornet, .22-250, 25-20, .243, .270, 30-30, and a .50 flintlock. I've never had to shoot one four times and if I had, I would not have documented it in slow motion and posted it on YouTube BECAUSE it is a horrible representation of our sport.
I've lost Ground hogs. I understand one can muff a shot. I don't believe in allowing "fliers" as an excuse while hunting. Fliers on paper not a problem. Fliers while hunting? You don't know your equipment well enough or you would not be excusing your misses by calling them fliers.
Two problems with the video. First it sends a very bad message about the sport. Second he CLEARLY failed to do HIS JOB when he bludegeoned that GH to death with a hail of pellets. One shot. Two at most. By the time you get to three you had better be kicking your own ass rather than bragging about your performance.
All this "tough guy" BS about not caring about making a humane kill in this thread is just childishness. If you don't value the life you take (even if it is a pest) you shouldn't be taking it because your head is in the wrong place. You owe that animal a clean kill.
You also represent all hunters when you post a video up on YouTube ~ That makes my opinion relevant.
Just my two.
