I've never used one but it looked great when I saw it in person. I modeled the reticle in Strelok Pro and running a .308 with 150 grain Winchester XP hunting rounds at 2700fps, all the BDC drops will ballistically match within a few feet of each other if you zero at 250yds.
I knocked 120fps off the listed 2820fps of the factory ammo which probably had a 24" barrel when they tested it.
Assuming you have the short 18" barrel Predator then adding this light weight scope would make a very handy package.
