Bart B. --- If I misquoted David Tubb...I want to make my apologies to David Tubb. No doubting, what you said is true ---that is --- hunting for mirages with your spotting scope at 1,000 yards. You can tell...I'm a novice, in long range shooting sports --- for the furthest I've shot --- is 200 yards, at the AGC gun range located on Marriottsville Rd, in Baltimore County, Maryland.
Thanks for the input.
