Maybe it's the ammo - BSA Optics 2.5X20mm Deer Hunter Scope - DH25X20 Riflescope Rifle scope

Former Marine expert, Coast Guard weapons instructor. Using scope on .22 Marlin Papoose stainless. Can't get tight group with hyper 22s. Hi vel a little better. Same ammo through other 22 scopes puts all in a quarter at 25 yds. I think there may be a slight focus/parallax problem with this model. Still, for the money, a good enough scope if you don't expect extreme accuracy.
Pros: well built, simple, clear, hi resolution
Cons: can't get'em in a quarter at 25yds.
