Couple of Questions? Been looking at these 2 scopes (BattleZone 3-9 and the Bushnell 10X Tact). Just how accurate are the range dial ups on the Battlezone? Are they really worth having or do you dial say 500 yds then have to make 3 more clicks on the elev knob? Do I understand it right that the Bushnell Tact has much more finer click adjustments than the 1/4 MOA on the Battlezone? Any opinions on having a 10X fixed over a variable? My main use will be to check ammo accuracy at 100 yds then playing out to 600. Many thanks.
