Catfish has given you good advice. Graybeard has also given you good advice. Get one with as long of eye relief as you can. You may decide to shoot some thing with a little more kick to it than the cast bullet stuff and you will be glad you got longer eye relief. I have used Shot gun style scopes for this type of fire arm. I have a Bushnell Banner 2-7 X 36 on my 444 Marlin (71-2736F). It has a 4+ inch eye relief. They usually have fixed parallax at 50 yards and have longer eye relief. You can get them in a variety of configurations from 2X fixed to 3 - 9X variables. I can not imagine you need any thing over 7X for hunting, with a lean toward a fixed power scope in the 2 to 5 X range. For target work a variable is nice (turn it down to hunt with and up for targets) but a 7X will work up to 100 yards very nicely.
