I guess I should have waited until after I did a brief search to ask the question about trajectory. In short order, I found and downloaded a simple reticle calculator program from Hawke Optics. It confirmed my suspicions. With my ammo and a guessed muzzle velocity of 1000fps, a zeroed in range of 15yds puts you almost a half inch low at 10, a half inch high at 30, and almost dead on again at around 40yds. The flattest trajectory on my set up would probably have me zeroing in the scope at around 20 yards, making me .2 low at 15yds, .1 low at 35yds, and still only a half inch low at 40. Cool software!
