I know it's out of your price range, But I'm going to throw a plug for my favorite chinese scope supplier and BDC.
Primary Arms 4x ACSS
I really like these reticles, they are fast and easy to use, and in the entry level scope game they are a lot of bang for the buck. I had both a PA and a Nikon on my .300BO the same day, and the difference was notable enough I sent the Nikon back and just went without a scope until the PA one I wanted was back in stock. They are also really nice guys. If you can stretch the pennies you won't be sorry.
If you have to stay in the $170 range, the nikon is your best bet. IIRC It's calibrated for XM193, so 55gr@3200-ish FPS
