On all my scopes. Athlon, Vortex, Hawke, Leupold. When shooting the pellet arcs up and to the left and then back down to the right to the POA. I would expect to see it arc up and then down in a straight vertical drop. Shooting 50, 75 and 100 yards is always the same with the added hold over, but I can see it pull to the left and back to the right. It's the exact same on different guns also. It's weird. Can't explain what I'm seeing. POA and POI are the same. This is with no wind. With wind it's just more pronounced. Is this some weird optical illusion maybe caused by my glasses? Sylvan
