most often charts need tweeking before a final version. first off chronagraph information is rarly
perfectly accurate. id be printing a chart and go shoot. the actual shooting results trump all other
factors at least on that day under those conditions. you will no doubt be tweeking numbers in order
to match what you actually did. that will give you a baseline to go by. your weather station can be helpfull
in updating your data on subsequent outings. another option and the one i use is sighter shots.
today there is alot of talk about first round cold bore hits even at extreme distances. no doubt in some areas
that would be more important than in others due to terrain. we shoot across wide valleys onto steep mountainsides.
sorta like shooting at a picture on a wall. misses can be quickly evaluated corrections made and follow up shots
on their way in seconds. im well aware not all areas are as easy as that. a miss may in fact be hard to detect as to why.
thats where a buddy acting as a spotter is very important.
