Yeah... it's not the rain but barometric pressure/air density that can.... which tends to vary during weather changes. Shots fired within a short span of time I highly doubt air density would change enough to matter... currently raining or not.He hit all targets out to 1000yds in the rain calculating wind and drop, ...thats using science.
More like... you got dialed in a couple few hours ago, it's raining now, and now you're shooting a hair low... type thing. Of course, even if the rain suddenly stopped... you;de likely still be shooting just a hair low.
Enter ballistics and distances into the mix and some may be affected while others won't to any noticeable degree.
Interesting questions, but so much is involved it'll twist your brain trying to extrapolate a simple set of rules. Like, shooting in the rain will or will not affect shot placement. Kinda like a "chicken or the egg" problem.
