Here is the 100 yard target. Its actually better than the 75 yard target, but I took more care in my aiming and did not run back and forth between shots. So I was not getting winded on this target. This is only a four shot group because I run out of black powder. I got two more last weekend but they were at home. My point of aim was not at the center, but centered between the top two squares. The first shot chronied 1350 but all others did not register as the sun had already set. The shot to the left, which was a two inch miss to the center of the other three, was just bad pointing on my part, not the fault of the projectile.
All in all, I have to say the Hornady's just shoot sweet in the Sidekick. These 385's, which I bought at a local gun shop, loads sweetly tonight and were not awfully tight. This must be why they registered higher velocities than the other night (to 1347 or so from 1329). Not sure how far I will be able to shoot them, but I think it will all depend on me and the precision of my aiming. The stability of the 385 GP's can not be questioned in my Sidekick, they are definitely stabilizing.
Here is the target:
