Rule for first riflescope, buy what you can afford today.
You can always get a bigger, better, badder scope down the road, once you are accustomed to using a scope, AND NOT USING IT FOR WHAT YOU BUY BINOCULARS FOR, you might get shot at.
I have used Tasco, Bushnell, Redfield, and Simmons as starter scopes.
I have always opted for, in low vegetation with hills and fairly flat terrain, the old 3x - 9x variable scope.
For those with lever actions, the standard was a 4x, or possibly a 2x - 6x with a little more terrain,.
The objective lens was a 30mm, and with a long eye relief, or long distance between exit pupil and eyeball, as would be placed on a bolt action rifle.
