Not all bullets are considered equal. Hollow points are designed to expand, as they expand they typically break up, to a degree, which is why they have measured weight retention in bullet ads. Full Metal Jacket ammunition does not expand and does not break up till it starts to tumble. If the bullet continues straight it won't break up. Armor penetrating ammunition is often a steel or tungsten core wrapped in lead covered in a copper jacket. That's a lot of materials that can break up if they tumble. The most interesting thing to test would be a dangerous game bullet of solid copper or bronze. That's just one solid chunk of metal that would be far less likely to fragment, period. On guns shooting under water. All guns will shoot under water. It's the ammunition that poses the greatest problem with them firing under water. Early flintlock guns will not shoot because the primers are a pan of black powder and it gets wet. Wet powder doesn't burn. Modern metallic cartridges are pretty well sealed and WILL fire underwater. Julian Hatcher, a retired U.S. Army major general, proved all this through extensive testing WAY back in the early 1930's. There have even been guns made specifically to shoot underwater (mainly just projectiles more suited for underwater "flight") Heckler and Koch P11. Bullet’s do not come apart if it hits something.

Let’s look at aspects of time which, to me, suggest that it has a somewhat fluidic nature. It seems to me that time responds to gravity, velocity, and physical masses in ways that bear some resemblance to the ways that water responds to them. The effects of time increase as one approaches a center of gravity, such as a planetary core, a star, or a black hole. Likewise, the effects of water increase as one approaches a center of gravity. As one moves faster, one approaches the infinite, the traveller’s mass approaches infinity, and time seems to all but stop (at least to the outside observer). The faster a body is traveling as it enters water, the more highly resistive the effects of water will be upon that body; consider the results of the famous Mythbusters swimming pool experiment with guns.

Check out the youtube video. That is one of the reasons they are the best handguns made. Glock 19 (and others) will shoot under water. Check out the youtube video.
