I really like the old Leuopold VariX III 3.5-10 with OA that someone put 3 dots in years ago. It matches the hummer trajectory with the plex cross hair at 100 yards, first dot at 150, second at 200 and third at 250! Just pure luck that it turned out. I never want for more scope and shoot the hummer a lot at prairie dogs. I've run a 3-9, 4-12, and 4.5-14 in Leupold and they worked well too, but my favorite is the 3.5-10. My brother likes his Burris 3-9 ballistic plex on his.
