I have the S+B on my Steyr LG 100 and I am waiting for a sidewheel to be delivered at the moment. However I scored 28/30 at Redfearns yesterday with it, so even without a large sidewheel it range finds very well. The optics compare favourably with the best that I have ever used and it has not whited out as yet, even when the sun is shining straight down the front lens. I have only ever seen this before with a Burris 8-32x44. I now have no excuse for missing the target under any conditions.
I will post an update when I have fitted and calibrated the expected sidewheel.
