I am in need of a higher magnification scope but cost IS a factor so have to consider all options. One option is to increase the power of the scope I have which is a 20X STS. Who has had this done, how much incease and by whom? Also how did you like it after the modification?
Ackerman advertises this service and I assume Parsons does it?

Don, you have the additional advantage of being fairly close (relative to so many of us) to Gil and his scope operation.  His place is South of you in the area just North of Cincinnatti, and he seems to always go to the Ohio Gun Collector's show if you want to catch him in person and chat.  I currently have a STS 20X at his place being restored at the suggestion of our mutual friend Dale53, but can't speak for his ability or willingness to change power of a scope.  I do know that Lyman once advertised the STS up to 30X so we can assume that much SHOULD be possible if proper lenses are still available.

DonH: I would look no further than the Sightron in 36X, you can price shop this scope and get buy for under 400.00 bucks. many NBRSA shooters use this scope and win with it. You can Google their web sight and find a lot of dealers with this scope. It is hands down better than the Leupolds at much less the cost.
