If your talking about 100 yrds. from the bench and 600 yrds. in the field I would recommend you look at the 15 x 30 Leupold. It is a little higher than the $ 200, your wanting to spend, but it is small and has the largest field of view of any scope I have ever seen in it`s power range. I have one in my pick-up on a window mount at all times. It is 1 fantastic hunting scope that can be used as a bench scope. I have a higher powered Leupold scope that is far better from the bench, but it cost a bunch more and it`s now near as nice in the field.
