I had asked a question on the effect Recoil has on a bullet's trajectory and got wonderful help from this site. Thank you! Now I have another question... I used to think rain had no effect on a bullet until I realized I wasn't actually hitting any raindrops, when I started hitting them, I noticed a big difference in the bullets point of impact. Unfortunately, this has caused an argument on specific firearm forum and I came here to ask if someone can do the math on such an instance. First a video of me shooting in the rain, hitting a raindrop, whereas my point of impact has changed being about 12 inches lower than normal at 350 yards. https://www.youtube.com/watch?v=dFyQLS2KXBc The picture displayed above shows the cloud made by hitting the raindrop. The strike was maybe 50 yards downrange of the muzzle, whereas it needed to then travel 300 yards further. Here is the variables of that particular shot. Bullet weight: 150grains the bullet design is like the one on the left. Muzzle velocity; 2360fps, every 50 yards it drops in velocity about 100fps. Normally, it drops height-wise 33 inches by the time it reaches 350 yards. I don't know what else you would need, just ask and I may be able to help. I know that a twig can make a huge difference in trajectory with the same setup at 575 yards. https://www.youtube.com/watch?v=wMvXm_GWUoc That looks to be about 35 inches low; which would be somewhat more than the raindrop. Thanks in advance! Edit by Borek: fixed the youtube tags.
