[QUOTE="justgoto, post: 786243, member: 17125"] I've made a video testing the POI of bullets hitting drops of water as opposed to those not hitting water... I thought it might be of interest. [media=youtube]UusiTSu1tSU[/media] Specifics: Howa 1500 30-06 Hornady 150gr FMJ, 2600fps Varget 46.6gr CCI 200 Winchester case 300 yards Dropper devise 260 yards from target Shots 3, 4, 5, 6, 8, and 9; hit water drops. They make an 8 inch group. Shots 1, 2, 7, and 10; did not hit drops. They make a 1.5 inch group. The group that hit water drops, is over 5 times the size of the group that didn't. Note: I thought shot 8 missed a drop, otherwise I would have taken shot 9 without water as I did shot 10. I couldn't see the water hits on the camera so I speculated from the POIs on how many hits on drops I had accomplished. I had preformed this test before; but it was very hard to see the hits in the other video, you can see the hits on drops in this video perfectly. The other video basically mirrors this test. I also wanted to note that a drop of water seems to simply deflect the bullets. I expected the POI height to be lower due to a velocity reduction; I don't think that is the case anymore. The POI shift appears to be random which denotes simple deflection. [/QUOTE]
