If all of my environmentals are imputes correctly, I take the approach of I don’t care what I need to tweak to make the data work.
Get your good (keyword) verified dope to whatever distance you want. The more data points, the better.
Then tweak your sight height (trick that is starting to pick up steam, that you’d be surprised works well sometimes), mv and bc (sometimes only one of the three and sometimes all three....just depends).
Too many people spend too much time wracking their brain because they don’t think the calculator should need something (insert MV, BC, sight height) and are always dicking around with bad dope or calculator.
Just do whatever you need to make the dope line up in the calculator and that the calculator gives accurate solutions when the environment changes.
It’s been about 7 matches since I started taking this approach of just making the data line up (I only use a chronograph for load development, never for dope) and I can count on two hands at the absolute most shots I’ve missed due to a vertical error. In temps from 50deg to over 100+.
