BSA is a lower end scope. In scopes, binoculars, etc. You generally get what you pay for.
#1 this scope will not be repeatable like a true target scope needs to be. So if you are a cranker then the odds are that your going to miss what your aiming at. If you do manage to hit it, it will be dumb luck.
#2 The glass on these things are cheap. glass trumps maginification. people tend to go for higher magnifcation but you are better to spend money on quality glass.
Whats your gun, what distance are you going to be shooting at, whats your budget?
If you want something to crank and good glass for the money:
If you can afford more, maybe look into a sightron big sky or sightron SIII
