I just bought a cheap Tasco Pronghorn scope. I mounted on my .243, as I dont have anywhere to take long shots. It has been a long time since I even used a scope. The problem I am having is that If I look away, and back through the scope, I can see the crosshairs plain as day and good, but the target is a blur in the background, and out of focus. If i look through the scope for any period of time, I can see an ant far off, but the crosshairs are gone. Is this typical scope shooting? Is it me/my eyes, or is it the scope? Is that how it works? How do I know where im gonna hit if the object is in perfect focus, but I cant see crosshairs?
