Went out this weekene and got hooked on .22 rimfire silouets (sorry, not the world's best speller). I've got an old Remington 512 that can deliver the accuracy, now I need a good scope. I'm looking at some Mil-Dots but all the old brands seem to be gone. (Bushnell, Tasco, Weaver, etc.) I don't want the price of a Leupold. What is a good scope with MilDot for no more than $150.00?
