This is my second Vortex scope. They are very good value and proof you don't need to spend a fortune to get a good scope. The 3-9x40 is a good choice for a rifle that you expect to be shooting out to ranges such as 300 - 400 metres.
My other Vortex scope is a 4-12X44 fitted to a .243. Target shooting at 200m you can see the holes appearing in the target with the scope set at 12 power.
