Re: terrible horibble miss
If your just holding over, then a scope built to dial would be good. The optics you mentioned are way to much IMO and will cause you grief if something is close, I've shot game a lot small a lot farther with the optic at 10X but dialing all I have to do is put the cross hair where I want the bullet! If you miss you need to figure out why before leaving the spot and I shoot an other shot at a rock or something to confirm why I missed. More shooting is better than anything, you will see a lot of guys going out and shooting rocks to practice ranging and doping LR hunting type shots, it's good practice!!
