Hi Dave,
I read that in Europe they have been using qd for decades.
Hunters over there trust the return to zero and only mount the scope when they reach the hunting area!! Granted, they may not be shooting that far, may get to go hunting more often and closer to home.
For me, I couldn't do that....not zero before a big event. Take off a day(s), get up early, pack up the vehicle, drive out an 1 hr before dawn, stay all day till everyone bags one.....that would be sick if shots were missed because the scope was off so you end being out till sundown and the other guys are irritated......or worse you hit Bambi instead of a buck and your friends never fail to mention it. (Don't ask. I still think my dad lied about zeroing the scope)
