I'm working on my form and trying to get some consistency in my 300-400 yard shooting (22-250). I need a spotting scope that will enable me to view my holes in this range and hopefully a bit farther. I'm not in a position to blow a pile of money at this point on a spotter. I've read a lot of reviews but most (and probably w/ good reason) tend to focus on the upper end units. I've read some good reviews on a relatively economical unit that is in my price range & wondering if anybody has had any experience with the Zhumell 22-68x90?
