Put this scope on a Gamo Big Cat 1250 pellet rifle. Sighted it in at 30 yards, and was able to shoot three pellets in the same hole.  Has kept its zero, and been very accurate.  Highly recommend even for center fire rifles.  I have Leupold Vari X III scopes on all of my center fire rifles.  If you are looking for an affordable scope, this is it!!
