I've got a 300 yard range close at hand. I went today out to re-zero my optic, reset the turrets and confirm my come-ups @ 300 to set myself up for some future endeavors. Since I was shooting ELD-M 140s, I figured why not use the Hornady calculator as a starting point. It was blustery today, in from my 9 o'clock or so. My MV is 2660 fps, the "try" was 1.3 mils. I did my best to shoot when it was calm; group indicates this was largely successful (I didn't hold/dial wind at all). 1.3 was good to go for my come up.
I was feeling pretty good...then noted that the "try" for that range and MV was anywhere between 1.1 and 1.3 depending on wind direction. I suppose 1.2 for calm conditions should have been the real deal. I don't think my come up was off. I guess the good news is that the trajectory deviation is never projected to by more than .1 mil from calm. That said, is it worth messing with inputs to square things? Do things even need truing here or am I just missing something obvious?
