I am saving for a either a leupold vx3L or a night force large power scope, not sure which yet. In the mean time I will probably buy a cheap scope to replace the olivion that i have as the optics are horrible. My father has a scope on a winchester model70 in 243 that is made locally and only worth about 200 dollars. he also has a 20 year old 8 times 40 leupold that he said was the best leupold he could buy at the time (not sure of the model) on a sako 17REM that I use. the optics from the cheap scope are about the same as the leupold in the day time and probably better at night with a spotlight. i will have to remove it from the 243 ro determine the accuracy because even with a borrowed schmidt & bender scope it wouldnt shoot under 1MOA. where as the .177 shoots an 11mm group at 175 yards.Is there any specific tests I can do to determine the actual quality of the scope.
