He took so long to shoot because he was trying to line up 2 deer.....? It seems from previous posts that he is in Nova Scotia and you don’t get two rifle tags here, so that’s be a dumb thing to admit to on a public forum, never mind the ethical issues.
I personally enjoy hunting with big bore rifles because I like them, I say have fun hunting with your .416 I’m happy to see that my .404 isn’t the only needlessly overpowered rifle in the Nova Scotia deer woods.
But there are too many people working hard to show the public that hunters are conservationists and ethical users of our wildlife resources, so if you’re going to try for a probably illegal and certainly unethical two deer with one shot, for the sake of the rest of us please don’t go around bragging about it on public forums.
