[QUOTE="31perersen, post: 2854675, member: 66782"] I shot them over the chronograph last night at 3450 feet of elevation here at the house, it didn't make sense but this is what the Calwell says for a string of 3. 2570, 2635 and 2601. wide spread and way faster that what I was expecting so I don't know if something was up with the chrono or what, it was evening and in the shade but I was expecting 100ish fps slower. My magnetospeed won't read with the suppressor on so I had to use the Caldwell. Just my opinion, but I would definitely not order a turret without validating my data first. If you have a range that goes to 4-600 yards, just input the G1 or G7 b.c. then use 2500 fps and shoot to halfway (300 yards) to make sure it's close, and adjust the speed if needed by using the drop difference and then push to the furthest reasonable distance you can, further the better, and readjust the speed to it matches your actual drop and give them that. I use a chronograph but only for a starting point then validate by shooting out to 6 or 800. After that I find the right data by doing that, I shoot all sorts of distances to make sure it matches up while having fun with it. Only 1 time did my chronograph reading and advertised b.c. data match my true drop, so I'd not order one even if I ran it over a chronograph without "validating" it first. Then you can feel 100% confident you're good to go at that elevation at least. I've also tested the precision hunter in several calibers for temp sensitivity and it was pretty solid.
