I know the differences between cheap scopes and expensive scope. When I chose a scope for my main deer rifle I did a simple comparison by looking into a heavily shaded patch a block away. The expensive Redfield showed everything clearly. The $120 Bushnell did not. I bought the Redfield.
Now I play with a lot of barrels, both Handi and Contender. Most of these are for shooting paper in bright sunlight. The others have expensive scopes. If I save bucks on a scope, I can spend it on more barrels.
When it is important, buy the best you can afford. When it is not, you can experiment. As I said in my previous post, sometimes you make out, sometimes you get burned. I can get burned quite a few times for the cost of some of the expensive scopes.
JMHO,
