Regarding hollow point's or bullet designs other than "Ball type".
Legality[edit]
The Hague Convention of 1899, Declaration III, prohibited the use in international warfare of bullets that easily expand or flatten in the body.[3] This is often incorrectly believed to be prohibited in the Geneva Conventions, but it significantly predates those conventions, and is in fact a continuance of the St. Petersburg Declaration of 1868, which banned exploding projectiles of less than 400 grams, as well as weapons designed to aggravate injured soldiers or make their death inevitable. NATO members do not use small arms ammunition that is prohibited by the Hague Convention and the United Nations.[citation needed]
Despite the ban on military use, hollow-point bullets are one of the most common types of bullets used by civilians and police,[4] which is due largely to the reduced risk of bystanders being hit by over-penetrating or ricocheted bullets, and the increased speed of incapacitation.[citation needed]
In many jurisdictions, even ones such as the United Kingdom, where expanding ammunition is generally prohibited, it is illegal to hunt certain types of game with ammunition that does not expand.[5][6] Some target ranges forbid full metal jacket ammunition, due to its greater tendency to damage metal targets and backstops.[7]
Along with a slick and a tune, taking rougly 4" off the magazine spring not only makes it easier to load and does not impede proper feeding of the action, it allows 9 rounds (instead of 8) in the magazine making it a nice 9 + 1. As one of my favorite people to read here says, "my grandfather advised that if you fire up a magazine out of either and still need more you either started shooting too soon or shouldn't have shot at all." ...which I find quite funny despite the very serious nature of the topic at hand.
