I am going to stick a bushnell 3200 10x40 tactical on my .22 'long range' rig when I get round to it, aiming to shoot rabbits consistently out to 150-200 yards with it if I can. The bushnell has a huge elevation range (90MOA I think) and nice big knobs, glass is reasonably clear and 10x is plenty out to 200... and best of all, it's cheap :D which is what .22lr is all about.
Planning on using subsonics, I will need to range each shot precisely as at 150 yards the bullet is dropping 4 inches for every 10 yards, that's a small margin of error to hit a 5 inch high rabbit. Should be good for learning the wind, too.
If it ain't a first round hit, it ain't nothin'
