I just got accepted into a new Hunting Club. It's mostly opened farm field shooting. A lot of nice deer come off this club. I'm getting over a pretty significant shoulder injury and I'm a little apprehensive about big bore shooting. The shots in this club can be out as far as 400 to 500 yds. What do you all feel about the effectiveness of a 243 Win on whitetail bucks (4 1/2 yr olds or better) with a 243 at these distances? I have a Model 14 that's a great shooter, its a 243. I'd look to use a round that close to 2900 fps out of the barrel.
