Here's the situation. At my local range, I shoot at a 440 yard target and a 620 yard target (distances provided by range and verified by laser range finder).
I'm shooting with my 260 Remington, 140 grain, with known good scope. I have shot long range for a little while, but have only more recently gotten serious about it.
Using jbmballistics and strelok for finding MOA adjustments, I find I need to adjust 38 clicks for 440 yards and 67 for 620 yards (they don't spit out the exact same number, but are reasonably close).
Actually shooting, I find I need to adjust 32 for 440 and 80 for 620. I understand that tables are just a starting point and you need real world dope to get hits, but I find it strange that one is over and one is under. I would expect if the table is off, it would at least be off with itsself. Example, for every two hundred yards, you have to adjust an extra 3 clicks to get the correct elevation.
I've played with all the temp, pressure, elevation, fps etc and can't get the results to fit without making entries that are obviously not correct. And even then, only one of the two distances will be correct.
Any thoughts? Am I expecting too much from the ballistics calculators? Just shut up and shoot? Haha, thanks.
