I should clarify,
I DO absolutely, highly recommend wearing electronic protection while hunting. I was never "bothered" by the noise without them but the damage was still done. With the price and performance of modern electronic protection, there's no reason not to use them. They actually IMPROVE your ability to detect an animal approaching AND protect your ears AND (if you wear muffs) keep your ears warm in the cold.
I just dispute the suggestion that flinching causes very many misses under hunting conditions. Most people don't notice recoil or blast in the excitement of the moment. Very many people (by far, most) flinch when shooting heavy recoil guns at targets, far fewer do so when shooting at animals. "Target panic", "buck fever", is another thing, but it's not flinching from recoil or blast.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
