From SAAMI: With the appearance of full metal jacket military 5.56 ammunition on the commercial Market, it has come to the attention of the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) that the use of military 5.56mm ammunition in sporting rifles chambered for Caliber .223 Remington cartridges can lead to higher-than-normal chamber pressures and possible hazards for the firearm, its user and bystanders. Tests have confirmed that chamber pressures in a sporting rifle may be significantly higher in the same gun when using military 5.56mm ammunition rather than commercially loaded Caliber .223 Remington cartridges, according to SAAMI. SAAMI points out that chambers for military rifles have a different throat configuration than chambers for sporting firearms which, together with the full metal jacket of the military projectile, may account for the higher pressures which result when military ammunition is fired in a sporting chamber. SAAMI recommends that a firearm be fired only with the cartridge for which it is specifically chambered by the manufacturer. yes, the military size is the same as 223 ammo, although powder loads may be higher in the military ammo
Depends on which military is using it. In the US military, the standard issue cartridge is the 5.56x45mm M855 cartridge. It is a 62 grain full metal jacket round. In NATO, the SS109 cartridge is standard, and this is also used by many non-NATO forces which maintain some degree of alignment with the West.

No, it is not legal to use full metal jacket ammunition for hunting in Texas. State regulations require the use of expanding bullets or ammunition designed to expand on impact for hunting purposes to ensure a more humane and effective kill. Using full metal jacket ammunition can lead to wounded animals and unethical hunting practices.
FMJ simply means Full Metal Jacket (no exposed lead on the bullet) and does not refer to a make of gun, but a style of ammunition. The link below is to a Wikipedia article on the .45 ACP, and shows a photo of the cartridge.
