I guess you could say almost all small bucks are killed by blind luck if you think most big ones are.
Its a fact most big bucks are killed by luck - the little ones ? Theres a heck of a lot more of them and they're stupider - right ? Anyone can kill a little buck, right ? But those old smart ones .......... no, they stumble most often or you and I would never even see them or know they existed during hunting season. I'd hazard to say 90% of the monster bucks taken were taken by guys who were not hunting big bucks and never knew that big boy existed in the same wood lot.
How can you feel all manly shooting a rut crazed buck chasing a doe ?
