Update. I got a really good deal on a Leupold rx-2800(less than $300). So I figured I would give it a shot. I have only done some limited testing but here is what I found. At 800 yrds it has no trouble picking up trees and non reflective targets in full sun 95 degrees. Speed is about the same as my Leica 1000R. My Leica will read the trees also at 800 but was limited to 600 yrds non reflective target(brown cardboard) same conditions same day. The leica glass is much better, but the reticle of the Leupold was easier to manage. I typically use range cards that I make myself after shooting at different distances because I never can get Ballistic calculators to match my trajectory. The RX-2800 comes with limited ballistics but I thought I would give it a shot. I know my bullet drop @ 600 is 62". So I picked the profile that matched and ranged 500, 400, and 300. The MOA correction was spot on from 600 in. From 600 out it was off by 1 MOA at 700 and 2,25 MOA at 800. I did not buy this unit for the ballistic capabilities but it is nice to know it will work in a hunting scenario 600 and in.
