thats just how it is man pellets dont shoot the same as each other..
Heavier projectile (kodiak) has more drop even though it has a higher BC. Its still traveling slower to the target and its HEAVIER, in which gravity has more time to react on it. And like others have said, its also a different pellet all together. Its head diameter, skirt diameter, weight, shape and length are totally different than the other pellets. Shoot those pellets out to 50 yards and you should see the same thing.The P.O.I. (point of impact) height or the measurement between the lighter and heavier pellets could also be the axis of the bore to axis of the scope relationship. In theory, our barrels on a gun are always pointing UP in relationship to our scope axis (LOS-line of sight). That's why a projectile will at some point (range) cross the scopes line of sight (guns zero). And all things fall to earth when launched. A heavier pellet traveling slower will fall faster (lower poi). Sighting in (zeroing) for the lighter pellets will have the same effectHope i said this right...........lol
