"Dog Soldier" is not real bright. Since I don't subscribe to stupid, I'll pass up subscribing to his channel. He said the gun is a "hundred and seventy seven caliber" and it shoots at 380 feet per second. This is cruelty to animals, if we define ethical as ensuring that our game does not suffer any more than necessary, and frankly I don't care much for rattlers myself. That is just not enough gun for the task. A big stick would be a better call. A ten pound rock would be a better call. Really that is just stupid and cruel on so many levels that it pisses me off... errrr. You want to kill something, kill it, don't torture it to death. That is probably just me though.
