you should check into the vortex scopes. In particular, the viper line is an extremely good value. I would put the clarity above leupold vxIII any day.
Maybe, maybe not. It really depends on what you are trying to accomplish. A higher scope mount gives you a longer point blank range.It will be relative to the scope you choose, the bigger the bell the higher the mounts. You want to have the bell as close to the barrel without actually touching it.
Thats the simplest answer.
PBR, or Pabst Blue Ribbon, is an economy priced adult beverage that is available at virtually any convenience store in the South-East. It shouldn't be consumed when you are sighting in your new optics, but may be helpful in your decision on what to purchase.Now that PBR has been brought into the conversation could someone go into it a little more in depth.
I would think the 20x would serve you better (depending upon your definition of "long range"), those .22s are hard to see at long range.I don't expect to hunt just target and long range plinking
