Thanks guys,
A little more info:
I would estimate 90% of my practice in the high desert, No cell signal.
Lots of sage brush, nice sturdy plant and takes a good wind to move it.
I have a Zeiss range finger but it doesn't calculate angle and the area I shoot isn't all that flat, But that's another issue to deal with later.

I usually take my Jeep out by past Lockwood, It lets me get away from the normal shooters and I can get past 1000 if need be.
I very seldom see another person in all the years I've been going out there
