Grandma can shoot a deer with a gun!
Seriously, I use them all in the appropriate seasons. Some big buck setups just work better with a gun. I still like to take the bow alot in gun season though. It' s just more of a challenge. On the other hand, it' s impossible to shoot a deer with a bow at 300 yards...or 200.. or even 100. So if you can' t get real close, the gun is the way to go.
