Hello everyone. I'm new to airguns and just purchased the Gamo Camo Rocket IGT to get started in the hobby. Having hunted deer for many years as a child, I have some experience in shooting. Right now, after about 200 rounds through the gun, it's grouping very well at 15yds, probably dime size when I'm doing everything right. If I move the targets up to 10yds the pellets still group well but are hitting low on the target. If memory serves me correctly, when shooting ballistic rounds out of a high powered rifle, my father told me that the gun will shoot low at very close range if the scope is sighted in for targets further away because the projectile is still climbing. Is it possible that is what I'm experiencing? Does anyone have a chart that shows typical trajectories for the average pellet at given distances from the gun? If my thinking is correct, then bringing the scope up to center at 10yds will make me high at 15, but dead on again at some other distance beyond that. Thanks!
