So what do we make of this. Is it real world.This came from a friend when i was asking to many question Here is an additional and plain answer to your question. It s clear that when its wet,â€¦there s less drag on the pellets. Hence the pellets will land higher on target and/or shoot flatter. This makes some sense of why when we see the â€œcalm before the stormâ€ we get noticeable differences? Ambient air density Air temperature, pressure, altitude and humidity variations make up the ambient air density. Humidity has a counter intuitive impact. Since water vapor has a density of 0.8 grams per litre, while dry air averages about 1.225 grams per litre, higher humidity actually decreases the air density, and therefore decreases the drag.
