Good inexpensive scope - Mueller 8.5-25x 44mm 1 inch AO Tactical Shock Proof Rifle Scope

I have this scope on a heavy barrel 10-22 that I use for sillouettes out to 150 meters with a 20MOA base, shooting the whole match on 25 power. Slightly fuzzy but usable at max power at 150 meters. A side focus would be easier to use. 1/8 minute clicks seem to be repeatable. This is the ultimate test for a target .22 scope. I hope it holds up in the long run.
