Jeff,
Hope this ain't a hijack.....
The weather is killing my Leica 1600.
Where there is plant of snow i.e., ground well covered, and hoar frost on trees it doesn't range worth a squat in any degree of sun light especially on south slopes.
When ranging to the shady side or when the sun gets real low and the south side is shaded I can range on a regular basis to nearly a mile consistently on sage brush, ground brush, rocks, boulders, juniper trees etc......
How's your's do in snow and sunlight?????
Wednesday there were 3 yotes in clear view from 590 to 688 yards for half an hour and I couldn't get a hand held range on them.
