Had the Leica from years back and really liked it for clarity and accuracy out to 1000 yards. Sig came out with their models and I grabbed an 850 on sale. Ranged a bull elk @ 776 yards (and later, his body at 137.5 yards). A friend worked out his range to where we could shoot out to 1000 yards and another friend has a 1500 yard range. So, I purchased the 1350 series.
As good as the Leica is/was, I'm sold on the Sig's.
