I have been using a Model 7 in 7mm-08 for 16 years. I have several other rifles / scopes , but the Model7 is about my favorite. Mine has a Nikon 4-16x42 Monarch on it. It is a wonderful combination and is a very balanced rifle. It will kill to 400 yards. But thats not what you asked.... you asked for a scope recommendation for around 100.00 , and not too high of a magnification.

I like some of the Burris stuff, the fullfield II is a good scope for the $$$.
I would not hesitate to get the Nikon Prostaff. The Buckmasters is a little better quality, but it is a fixed power......
The Bushnell Elite is a great scope, but it is more $$$.
The Weaver is a pretty good scope.... better than the Simmons stuff and the lower end Bushnells.
It all depends on just how close to 100.00 you have to be.
Use the links in the post, and it will take you to theopticzone.com.
You can look around there to see if you like anything better.
I deal a lot with Jon and Tammi, they are good folks....
God Bless
