I really like Sightron SIII 8x32x56 however it did not come with zerostop, like NightForce. Do I really need "zero-stop"? I wondered if I set up the zero at 100 yards and remembered the MOA or MIL number on the turret. (Sightron). When I'm done shooting and I can dialed down to the specific number which is zero for 100 yards. You know what I'm talking about? For ex. I have a wrench torque and I set up at 90 psi and torque the wheel nuts and I dialed it back to zero after it is done. I'm using it for F-Class and plinking/deer hunting. I have 6BR custom rifle without scope.
