For those of you that have these or have used them at medium to long range, will this work well enough to be able to shoot standard silhouettes out to ~600 yd? I was able to get time today to go out to one of our farms that allows for safe shooting out to a little over 600 yd. My Aero 6.5 Creedmoor is like the "easy button" at that range so I would like to be able to night shoot out that far. I have illuminators that have that kind of range, I'm just worried my PVS-14 behind the scope is going to run out of gas at a couple hundred yards. It is soggy as shit out there after hours of light rain, so can't get out to test right now.
