I'm changing scopes from the current fixed 12X Leupold to my 6+24 Bausch & Lomb Balvar. Both have crosshairs without target dots. I'm thinking the variable power will give me more flexibility with the rifle.I have used a Fixed Power 16X Leupold for Pdogs for many decades with a heavy Barreled 223 out to about 450 Yards , usually less . I have never found atmospherics ( heat waves ) or range limitations ( using 40 gr. Vmaxes ) where I wanted more than 16X ..... well ..... maybe a few times off a Bench ! That being said , I'm guessing you will want a Variable , so the 6-24x or 8.5-25X Leupold should work out fine for you . For Pdogs , where most of the time I'm wearing my darkest Sunglasses , I think any of the Vari X variations will work if you buy used . You might also want to look at the various Reticles as that is really a personal choice .
