Scopes gather light...
Plus a bullet 6" inches off target will still do quick work of dispatching the animal (in most cases), more room for small error.
Example - I've had deer come in with legal shooting at 40-50 yards,
and all I can do is place the cross hairs on the ground 6" behind it's front legs,
then slowly raise the crosshairs until I'm in the middle of it's chest (blob).
I would never attempt this archery hunting even at 10 yards!
Gun = hand granade
That's what I figured you meant, Ed. I bought pretty nice scopes on my rifle and ML. But, I swear....I must be doing something wrong (or, I'm just not used to hunting with a gun). My old eyes are pitiful in low light, looking through a scoped gun). I get ticked every time I go, thinking "if I had my bow, I'd still have shooting light. When I come out of the woods, it's still plenty light....lol.
I do hunt with a gun/ML in the thick stuff, though. My 2 (in my life) firearms kills were 20 and 25yd shots.
