Bullets bouncing offa water
In my thread about target shooting on the water, someone mentioned
bullets bouncing back and had a vid of this happening when a .5 cal bounced from a steel plate. First, some easy to remember physics: Light things do not transfer energy to heavy things well, that is why the bullet bounced back from the steel plate. Heavy things do transfer energy to light things well which is why sand absorbs energy from a bullet so well. Although a bullet will bounce at a shallow angle from water or sand, I doubt it is possible for a 180 degree bounce to happen. OK, it is "possible" but it is probably more likely you will get hit by a meteorite twice. |

OK, it is "possible" but it is probably more likely you will get hit by a meteorite twice. A friend of mine learned about bullets bouncing back and geometry all in about a second. There was a bridge that crossed the creek at a sharp angle which created a pocket that was a triangle between the abutment and the bridge. He decided that was a perfect place to put the cans he was shooting at. He lined up the rifle and shot. The bullet left the gun, hit one side of the triangle, then the other side, came right back along the gun barrel, enter his skull just above the eye but below the bone, and passed out through his temple. Fortunately he did not plan it otherwise he would have been dead, since he could not have set up the shot so perfectly. I think it is physically impossible for a bullet to make a 180 when it hits the surface of the water. To make a 180 it would have to hit something like steel or concrete that would reflect the bullet back on its original path. |

Here's a hint: make sure the hole in the barrel is pointed away from you. I mention that because you seem to have extraordinary problems with ordinary objects. |

OK. here is how you could get a 180 degree bounce from water. You need a very large breaking wave and I do mean large as the angle for reflection is less than 20 degrees meaning you need 9 reflections from the braking part to get your 180 degrees |

I play around with handguns quite a bit at the range, and before I start shooting, I spend a few minutes thinking over gun safety and looking around to make sure I've done everything possible to minimize the possibility of an accident. You seem to approach life's dangers from an opposite point of view. If it is foolhardy, risky, and it presents a possibility of serious injury or death, you're all for it. You would last maybe five minutes at the outdoor gun range I frequent before the range officer would ban you for life. |

Neat thing happens - you shoot the ice at a slight angle and the bullet enters the ice and travels a bit until the steam builds up enough - the bullet will come screaming back out of the hole and at pretty decent velocity. :) |

Yur not gonna get a 180 reflection of a bullet from liquid water, not gonna happen. Yes, being an optics guy, I know bout corner reflectors. |

Yes, you could really make a mess of your drink that way. Us Florida natives who rarely see ice outside of iced tea all had this mental image of someone shooting at someones tea glass. Srsly, I wonder how may generations it will take for people shooting up in the air to give us some perspective on Darwinism. So, nobody can think of any real reasons not to target shoot at sea? It seems to me that this would be safer than on land as I can be certain there is nobody within bullet range whereas on land you never know if that is true. (OK, perhaps there are Ninja scuba divers out there). |

You can't explain your latest round of idiocy in a sentence? I recall you wondering about warding off pirates. Usually the pirates are after boats a little fancier and faster than your little sailboat. How are you going to outrun or outgun a pack of pirates in a fast motorboat? Perhaps you ought to concentrate on learning how to boat without breaking stuff. |

MY next invention, just for rec.boats, a blood pressure monitor that disables the "send" button when Harry's blood pressure goes above a certain level. It'd cut his posts by 99%.

There's no Pirates in my part of the world in this century. |

One of our hay fields is a natural berm at a pretty good angle and we use that all the time for target practice. I don't think I've ever seen a ricochet from shooting although it's possible. |
