My votes if your dialing in. Under $450 in order of price Bushnell 3200 tac 10x40, swfa ss fixed power x42, bushy 3200 5-15x40, vortex viper (pick your poison) mag and objective.......For $450-750= Bushnell 4200 tac 6-24x50, vortex viper pst
6-24x50, sightron siii 6-24x50.................The bushnell tacticals have served me well at all levels, The swfa ss are typically very reliable as are the vortex and you may just barely get into a Sightron siii lr if you shop around. The more you spend the more likely you are to really appreciate the scope every time you use it. My list here includes essentially tactical scopes because they are already configured in what my experience suggests is ideal for lr-hunting, it covers a vast range of glass and size while retaining what I believe to be adequate reliability and a useful reticle. Your personal preferences may be very different but if I where you, these are the ones I would be looking at in those price ranges.
