Hi there i have had one in the past thought it was a good scope for the money,if you're after one go to optic warehouse on the net good prices bought from there before if you do get one mate i would only put it on your 17
For the 22-250 i would go for a schmidt or a zeiss both very good scopes I've had both not cheap but worth it haven't had one yet but nikon are meant to be very good too so have a look at one if you get a chance
