I am not very experience shooting with a scope. What distance do most of you zero your scope at? I'm sure it will depend on what your normal range is, but that's kind of my point. I shoot mostly in my backyard range, 25 yards. Shooting .22 at 50 was a large drop in POI. If I zero at 50 am I going to have to compensate much when I return to 25? Or should I leave it zero at 25 and just learn to compensate at 50?
