RE: 400 yard trophy?
Growing up in southern ag country there are huge open fields, some miles long. We commonly shoot predators at ranges of 300 - 500 yds. I will agree an untrained/unpracticed shooter does not need to attempt this shot but myself and a lot of my pals can shoot 3" groupings consistantly at these ranges. Thus I would not be nor never have been afraid to take this shot. I feel more confident shooting a standing deer 400 yds away in a field than 75 yds away through timber risking bullet deflection. Having made these shots now for around 30 years, yes I would do it but theres people Ive hunted with that couldnt hit a barn at 40 yds but are self proclaimed expert hunters because they watch the TV Shows and Videos.
