Hope your Tasco does OK by you!
Bought one a few years ago, as I wanted the higher 12X on the variable. It also had an adjustable objective.
However, the scope just was not sharp!!!! In no way, at no range and with no adjustment.
So that, along with a very bad trip with an early TC "classic" got me to looking for some quality.
Ended up with a Clark Custom 77/22 on which I installed a Leupold 3x9 EFR.
Great combination and great scope, clear, sharp, zero paralax when adjusted for range.
Hope the combination does well for you. enjoy!!!!!!!!!
Keep em coming!
