You stuck on Nikon? For bow hunting/medium range rifle I use the Sig Kilo. Very accurate and easy to use. If your just looking for bowhunting and possibly shotgunning, Nikon should treat you fine. Which model?? Im not to familiar with them, so I'd suggest something with a ballistics compensation( measures angle and give you true yardage)
Always remember,, if it states 800 yrds, it's probably good to 5-600 yrds. The amount it's rated at is in real perfect conditions which we'll never see when we need it.
