Boy this opened a long closed door. Found myself skimming FM 6-40 Filed Artillery manual. We used to have to keep all that in mind when firing - drift, bore condition, rotation, temp of powder, temp and wind speed at altitudes. All books and slide rules. No calculators - Ok we had one but took 4 to comfortably carry so it frequently got dropped. Get info, fill in chart, get standard adjustment. Ages ago.
