I have been shooting .22 LR on pests at long range (100+ yards) most of my life, with just iron sights or simple 4x or 6x scopes, but in the the last few years, i have used several different graduated reticles and target turrets.
I began with a 4-12x40 AO airgun scope with 1/8 minute turrets, to test ammunition. But I took it to a dairy farm to eradicate some pigeons, and built a range card beforehand out to 200 meters. It proved to be quite effective, and and left it on for a while, for squirrel hunting. It seemed too large for even a .22 the size of a centerfire, so I tried something smaller.
I put a Burris 2-7x35mm Ballistic Plex on there, and this was really the trick, about perfect. But I thought the parallax adjustment might be a good thing for a .22, and the Burris had to go back onto a deer rifle.
I ran across a deal on a Hawke Sport HD 4x32 with an etched mil dot reticle. This worked really well, too. The dots are 9 inches apart at 100 meters, which means putting the target halfway in between at 100, and the first dot down at 150... works great. The crosshair is fine and sharp.
So then I bought a Hawke 2-7x32 AO, which is certainly nice, and not much money, either, and small enough for my tastes.
Bushnell has started making some airgun scopes again and .22 and .17 scopes in 3.5-10x32 AO, with just a duplex reticle, and drums for .17 and .22 which you can install yourself. This may still be slim enough to suit me, but I don't know if I want to twiddle with turrets when I have 7x doped out to 200 meters with a .22 LR.
I know a lot of you over there shoot rabbits and pigeons with honking big scopes with turrets, so I thought I would ask how that works for you. I can see it being great from a fixed hide where you have measured or lasered the range, and maybe even shot some targets at spots on your range card to note the turret settings, but I wonder how it will work for walking, spotting and stalking pesky pigeons about a farm. I just have to stand and shoot, with maybe a post or tree for a rest, maybe just offhand, to 200 yards, with little time. The Bushnell, at $79.00 discounted, is so cheap as to tempt me.
A Leupold 3-9x33 EFR would be really nice. So would the little Burris 4.5-14x42 AO made for the short magnums, but both seem extravagant for a .22 LR.
