"I did find a bobcat while still-hunting at 10:00 AM Sunday morning. I walked up on him and took the shot at 35 yards."
We can stir this bucket all day and it's just gonna keep raising a stench.
I don't care what anyone else does as long as it's legal. You answer to your own sense of ethics, not mine.
As for my own self, I practice enough to know the range and conditions that I can make a killing shot and I work within those limitations. I'm not afraid to pass on any shot that I am not confident with.
However, when I see something I want to shoot and it's within my ability to hit it, I don't dick around trying to get closer or puck around with gadgets. I just shoot the damn thing.
Know (not guess) your limitations, work within them and you'll never know regret.
