I am very happy with my leica 2200 hd-b. First trip to the range with my leicas I found that the #3 ballistic curve matched perfectly with my 22 inch 6.5 creedmoor jp lrp rifle/prime 130 grain /srt arms xlti 9 inch suppressor/athalon cronus moa, all the way out to 600 yards. I was expecting to have to make a custom curve. This was using yards, moa, 1/4 moa clicks, 200 yard zero. Now I need to get out west so I can check it at longer ranges.
