[QUOTE="Alan Griffith, post: 676813, member: 4686"] I hear ya! I opened up my new 1600-B yesterday and the instructions are sometimes hard to understand. At lease the unit is easier to set up than my original 1600. I was able to range some dark oak brush out to 1975 in evening light. From an upstairs window I ranged the following. Compare Shooter to Leica 1600-B Curve #3 Yards- Shooter clicks- Leica clicks- 138 1 0 149 2 1 156 2 1 230 7 6 256 9 8 303 13 11 413 22 22 440 25 24 470 28 27 472 28 28 520 33 33 531 35 34 553 37 37 693 53 56 725 57 61 802 67 74 841 72 81 852 73 83 873 76 87 These are all pretty much horizontal distances. Will try and get out this evening to the canyon behind my house and range some "up" angle items. Found one target at 877 yds and it would not give me a firing solution. The spec sheet in 800m/875 yds is max for firing solutions. Was pleased I got the one @ 873 yds. I used the 100 yd zero and the when looking for the appropriate 100 yd zero reference chart in the back of the booklet, on pg 181, it gave the 12 curves as EU (European) for meters instead of US (United States) for yards. A simple misprint but had I not known what I was looking for, i'd have been lost and frustrated waiting for Leica CS to open up Monday am. The old 1600 manual only goes to 300 yds while the new 1600-B goes to 500 yds for the zero range charts. Looking at my results and the zero range charts, it seems everything is hunky dorrie until around 500+ yds at which time the two curves seem to depart a little more with increasing distance; as much as 2.75 moa at 873 yds. It may be I need to use curve #2, a bit flatter curve. I'll more this evening. At 300 yds my Shooter program says 9.76" low and the chart says 9.6". Yet at 500 yds, Shooter says 41.1" and chart = 45. Curve #2 @ 500 says 42.1. I'm probably confusing the heck out of everyone with this chart stuff. The chart is used to help the user decide which curve to use. Curve #3 is pretty much spot on out to about 500 yds; beyond is where the divergence starts. Alan [/QUOTE]
