RE: Westerners; what magnification for deer and elk?
800 yards?!
Having hunted elk and deer in WY for 30+ years, I've never found myself wanting more glass. To the contrary, I've often found myself wanting less.
My favorite combo is a 1.5-5x for elk, and a 3-9x for deer and antelope.
Seriously guys, I don't know where you're finding these long ranges to shoot animals at? Last elk I shot at less than 50 yards, the last deer at 150, and the last antelope at 100. The rest of the time, there's always either too much timber in the way or too much wind inbetween to reliably and responsiblykill something that far away.
