I've found them useful on light kicking rifles the kids have been using. My daughters 260 shooting 140 accubonds is extremely accurate yet starts to drop a bit a longer ranges. I wanted to use it last fall and by using the turrets which we practiced with out to 550 yards, we were able to easily center punch game animals in the 350 range. Again, lot of drop, but no worries and no need for magnum recoil to flatten it out.
I will second Steelie's comments and add that I find it a huge advantage to not have to have the scope on max power to utilize the turrets effectiveness.
