You might want to try this, set your near zero at 20 yards. Shooting at 885 the second zero is 45-46 yards. I'm using UTG medium mounts. This shoots about 3/4" high in your mid ranges say 35-38 yards. you have a 1 3/4" at 5 yards 1" at 10 yards and 1/2 inch at 15 yard holdover. I initially had the gun shooting at 920, the second zero was about 60-61 yards, the mid ranges had about a 1 3/4" high trajectory. For me it was easy to screw up the hold under at those 35-50 yard shots. This is using a 30 mm tube scope, coincidentally it works out almost identical with a standard 22 Cricket with the same scope and mounts.
