What are your recommendations for a .22 LR precision target scope. I probably won't be engaging in true benchrest or PRS competition, just informal 100 yd + target practice. My Ruger 10/22 with heavy Kidd barrel and Boyds laminated target stock is a heavy rig that I only shoot from the bench, I won't be taking it to the woods to hunt small game. So I don't want your standard rimfire rifle scope. Currently I'm using a Leupold Mk AR scope 6-18x with a one inch tube. It is only marginally adequate. I'd prefer a top magnification of at least 24x, a 30 mm tube and something more precise than a simple duplex reticle. Illuminated reticle is not really needed as I probably won't use in low light situations. Not looking for top dollar glass, something around $500 +/- perhaps?
