Bought this scope recently for its ability to focus at very short ranges but took it to the club and tried it at 25m and just could not get the target in sharp focus... Anyone know much about this? I'm wondering if being set up to perform at very short ranges means it's out of its comfort zone at moreusual ranges? Also struggled to group well which I wasnt sure if possibly due to parallax error? I thought an AO scope would eliminate this but perhaps not? Any advice gratefully received!
