Sounds like some good shooting.

As for a good scope, try a Nikon Pro Staff 2-7x32mm without the BDC or a Nikon Pro Staff 3-9x49mm with the BDC. Let me state, most of them BDC scopes are set up for a magnum charge with a 250 grain bullet. So while you could learn the marks on the scope for the load you are using, do not take their adjustments as gospel to your load.

In my rifles for long range, I was shooting one afternoon with a T/C Black Diamond XR and 100 grains of Pyrodex RS and a 250 grain Shockwave. I was shooting at a paper plate of a set of sticks in the hay field. I discovered that if I used the fat part of the cross hairs and held that dead center, it would throw them Shockwaves right into that plate.

I like the Nikon Pro Staff. It was recommended by a man that shoots competition and owns the gun shop that I keep in business. He told me for the money there is not a better scope out there. Most of them are around $129.00 and some refurbished are $99.00. That's a heck of a scope for around $100.00. Also I go with the 2-7 power. As a lot of the old timers will tell you, before there were these fancy power scopes, we used to shoot that far with a straight 4x so with a 7x I have all the power I need out to those distances.. Also they are a shotgun scope so they have more eye relief.

Get good glass, and learn your drop. Even with a BDC you have to know how far the object you want to shoot is. After that I can adjust my hold if I have to. Most of my shooting is 50 yards and under unless I hunt the hay fields. Then I could see a 200 yard shot, but I seldom hunt the hay fields. Those opportunities come when walking out to the woods...
