[QUOTE="BallisticsGuy, post: 2525389, member: 96226"] It's called angle of repose and it's a real thing but you have to keep in mind the angles involved are tiny. If you run 60moa of up you're at 1 degree of nose up attitude. 60MOA is the kind of dope you need to reach out to something like a mile with a rifle cartridge capable of getting a bullet there supersonic. I've seen ballistic effects that seem to suggest there was nutation of the bullet, actual drop curves being lumpy vs smooth predicted drop curves. At the receiving end it doesn't really matter for bullets because even if they don't expand in the textbook mushroom they're liable to fragment with some part of the tip breaking off and forming its own wound channel. That's kinda how M193 projectiles were meant to work. They don't "expand". They "fragment" which is totally different because of the spelling. [/QUOTE]
