I had one...sold it. And just bought another 77/22 VBZ yesterday and scope is coming! I like the 50 yd zero myself and my other 22 mag LOVES the Remington Premier 33gr vmax/accutip bullets! They are lasers out that thing and shoot sooooo consistently for a rimfire!

As for trajectory, a 50 yd zero makes life easy out to 100 yds. At further distances, i havent done much work with it.
