Flintlock Weapons Mod for Minecraft 1.5.2/1.5.1/1.4.7

Features:

Four new flintlock weapons
Two ammo types
Unique reloading system
Fitting and balanced with the game, not ridiculously OP like most gun mods
Taking suggestions from the community and actively looking to improve and update the mod
Easy, quick installation (only ModLoader required)

This mod adds four new weapons: Pistol, Double-Barreled Pistol, Musket, and Revolver. The Pistol fires a bullet, a one hit kill on any mob, and must be reloaded after each shot. It also isn’t too accurate. The double-barreled pistol and revolver do the same, but can hold two and six shots at a time, respectively. The musket fires one shot at a time, but is extremely accurate while requiring twice the gunpowder to load. It also has a bayonet, allowing it to do damage equivalent to an iron sword while melee attacking.

Loading these flintlock weapons in real life is quite cumbersome, and this mod replicates that. To load a weapon, you must craft together an unloaded one, gunpowder, and your ammo. The multi-shot weapons can do this multiple times to become fully loaded.

There are also two different ammo types: round shot and buckshot. Round shot can be loaded into any weapon, and fires a single, damaging bullet. Buckshot can only be loaded into the pistol and double-barreled pistol, and fires a spray of bullets that can damage multiple enemies.

A bit about the damage:

Pistols, Muskets, and Double-barreled pistols are a guaranteed one-hit kill on any regular mob (excluding the ender dragon and wither). As I don’t fully understand the projectile damage calculations in minecraft, I just threw random numbers in until it was balanced the way I wanted it. So I can’t exactly tell you how many hearts of damage a shot does, but it is at least 20, as that’s how many hearts a zombie has, and they can be killed in one hit. With the revolver and any gun firing buckshot, however, the shot may not be a one hit kill. Specifically, a bullet has a 1 in 4 chance of not being a one-hit kill. This was due to the revolver and buckshot being a tad OP.
