dmoran , I have one. The sightmark 8.5-25 x 50 and I'm putting it on a 22 cal magnum springer Hatsan 125 sniper . If it can make it on this gun with out falling to peaces and it holds it's zero and it tracks like it should , it should make it anywhere . The Hatsan I have is the most powerful springer made today and has the worse recoil of all the springers . I choose this scope because it is #1 airgun rated #2 has a lighted reticle green and red. The lighting I think is really nice and does not bleed out so you can still see the mil dots , it has 5 settings and the lowest is all you will need . #3 it has a 18mil or 60 moa adjustment so with out a tilt it will give me 9 mil adjustment which is enough to get me out to 180 yards and still be on a mil dot . 180 yards puts my pellet at 6 fpe which is its limit for squirrel and rabbit and thats the reason I have the gun and scope combo . #4 it has a close focus of 10 yards with a side parallax that I'm going to put a 100mm wheel and mark each yard from 10 to 180. #5 is because it has a 8.5 to 25 power adjustment .Because when your using a pellet with just enough power to kill small animals at 180 yards you have to be able to hit a quarter size target or smaller . The 8.5 with the 10 yard close focus will be good for the under the tree and shooting up into the tree for squirrel or coons . #6 The lens . I have been looking through every scope in every store in a 500 mile radius and I'm my no way a expert ,but I do consider my self a amateur photographer take a lot of photos with a top of the line pentax k3 camera and top quality camera lens,so I think I know what good glass looks like and I must say its camera lens clear ,in fact I'm going to mount my canon g10 on it and take a few wildlife photos with it . I'll post them when I get it all setup . Of course all the above reasons don't mean a thing if it doesn't track or hold its zero after shooting it a few thousand shots which in pellet talk is only 4 tins of 500 pellet in each tin and thats in a weeks time . So again If it can stay together on the inside after use on a magnum spring air rifle , shot after shot then in my book its a good scope . I will keep you posted on how its holding up on its tracking , zero and lens staying put from the shock. Here are a few pics of the reticle hand held so not the sharpest but its good enough to see what it looks like in different back ground light. IMGP0733 1 by myridevlx600, on Flickr.
