memtb, I thought it was obvious. OP felt that the intrepid 400 yard long rangers needed his help to sight in. And since it is obvious they are not members here, he had to 'help' post their hero pics for all to fawn over, even though there are better ways to insure success at longer ranges, than the method they chose.
Merely conjecture here: But, perhaps there's good logical reasoning for this approach!
#1: Perhaps his friends came up from much lower elevation, and as many here have advocated…..re-zeroing at expected elevation is prudent!
#2: Perhaps he knew, within the bounds of reason, almost exactly where and at what range to expect the elk!
I have a friend that hunted a particular area for most of his life, he's pushing 60 very hard. He knows the area like the back of his hand, and has killed several elk, that without deductions for broken tines, ect., are well into B&C class…..one hypothetically in excess of 410!
He knows that during the first day or two of the elk season opening….the exact pass/gap where the elk will move once the hunting pressure starts. This gap/pass is around 850 yards from where he sets-up for the almost inevitable shot! He practices all year at that distance! Yes, he ranges the elk when they're crossing, as 50 yards plus or minus @ 850 yards is far more critical than 50 yards @ 400 yards!
Sometimes there are very logical reasons for decisions made…..even though we may not know the reasoning behind those decisions! memtb
