There are companies that make custom turrets for many scopes. I have one from Kenton Industries on a Sightron scope, but some of the ones I've used with Night Force and Vortex scopes seemed nicer. Like jackelope and carpsniper were saying, as long as you get very accurate load data and then practice, they're a great tool. As far as the Huskemaw scope itself goes, I've never gotten the chance to use one but I have heard good things about them.
