I Have one
I have used off and on for a few years. I like mine. I tried it on my Myers action the other day and was able to adjust it easily @ 50 yards. Some things to note, however: keep the set screws tight on both the turrets and the tensioning threaded plug that holds the spring. I discovered mine had come without a set screw for the tensioning plug when the scope was on my 30 BR HV rifle causing shots to go waaaaaaaaaay over there. Also the turrets WILL MOVE, from recoil if the set screws applying tension the turrets, to keep them in place, are not tight. Got to love the Bomb to shoot them 30's, eh!
