Well as long as you are going to figure out "All the factors" don't forget powder position sensitivity. That can be a real biggie too.
Just a guess on my part but once you zero your weapon at 1000 yards, fire for effect and hit the x-ring, game animal, or enemy combatant (if you are firing a 155 for example) you probably have or wittingly or unwittingly properly applied all the factors to your weapon of choice.
Course you could always calculate "All the factors" in the field depending on the direction you are shooting. Armed with a good compass and taking into account declination, spin drift etc. Your game animal may be in the next state by the time you shoot but what the heck at least you will have all the correct data.
baaa haaa haa, trouble maker. I tend to load my data in the computer at first light and while in the field I double check it. Then if a firing solution is needed it is much quicker and simpler. Of course I have my chart as well, for known elevation. Correct me if I am wrong but if your properly load your data it is not that time consuming to get a good solution. For me I have data perimeters loaded in with the variables being range, slope, absolute baro, temp, wind speed, wind direction, and CE. I can load absolute first thing at the hunting site, as well as temperature. That leaves range, slope, wind, CE. I can get range and slope from the Leica with a press of 2 buttons. The rest hardest part is CE. Lat is already loaded. so I need 1 numbers, compas direction, that I would not normally input if CE was not accounted for, correct? When in the field I time myself for practicality sake. It does take a little time for sure, but I guess after all if you are shooting a 1000 yards it is about the shot and not the hunt so it better be a good one.
