Steve,
In hunting season this year, with lots of snow on the ground, I ranged 1220yds to a pine tree, with snow on it, handheld, through the windshield of an explorer, in bright sunlight with my Leica 1200.
That was the farthest I got it to go. I had no trouble getting 1150's all over the place. I would guess that the reason it won't range farther is because of the firmware in it. It ranges 1100 or 1200 yds as fast as 25, and won't go past 1220?
For the real "Up North" guys, they may like the bushnell better because of the LCD display. If you are hunting near dusk, the LED lights up and is difficult to see past to aim the unit. Some of the Canada and Alaska guys talk about hunting when light conditions are sub-par and I could see where that would be a problem. Forget about ranging anything at night unless it has a light on it. You'll never find the thing with the LED on.
My Bushnell YP 800 would not range 400 yds in daylight. My Newcon 1500 wouldn't go past about 650. I figure, the price per yard on the Leica is far less than the competition.
