The Core-Lokt bullet design is the original controlled-expansion bullet and one of the most effective ever developed. Its progressively tapered copper jacket is locked to a solid lead core, promoting perfectly controlled expansion, deep penetration and high weight retention for dependable results.

Brief history on 3040 krag
Although the US Navy and Marine Corps had used smokeless powder and bolt-action rifles in small numbers, the US Army was the first to adopt a cartridge that was made specifically for smokeless powder, the 3040 krag ammo. It was modeled by the.303 British, with which it shares many geometrical similarities. The.30 Army loading was established in 1894 utilizing a 220-grain (14-gram) metal-jacketed round-nose bullet and 40 gr (2.6-gram) of nitrocellulose powder following a brief experiment with a 230-grain bullet loading The 30-40 krag rifle’s 30-inch (760 mm) barrel of this loading produced a maximum velocity of 2,000 ft/s (610 m/s), and the Krag carbine’s 22-inch (560 mm) barrel produced a maximum velocity of 1,960 ft/s (600 m/s).
Other names for the rimmed 3040 krag ammo round include.30 Army and.30 U.S. Despite being the first smokeless powder cartridge used by the American military, the.30-40 Krag kept the “caliber-charge” naming convention used for earlier black powder cartridges, i.e. a.30-caliber bullet propelled by 40 grains (2.6 g) of smokeless powder. A single shot in 30-40 was the first smokeless powder round fired by Winchester, and it was one of just three rounds for which the 1895 Winchester lever action, unveiled in 1896, was first chambered.
The 3040 krag ammo quickly established itself as a favorite for hunting and was installed in a number of different rifles. The.30-40 caliber Krag was used in 1899 to kill the Rocky Mountain elk that set the world record. Until the second half of the 20th century, the record remained in place.
In an effort to mimic the ballistics of the 7-57mm Mauser cartridge used by Spanish forces in the Spanish-American War, U.S. Army ordnance authorities created a new loading for the.30 Army cartridge used in the Krag rifle in October 1899 after studying the lessons learned from that fight. The new loading raised the Krag rifle’s muzzle velocity to 2,200 ft/s (670 m/s) at 45,000 psi. But as soon as the updated loading was published, reports of broken locking lugs on service Krags started to appear. The arsenals received the remaining supplies of this ammunition (about 3.5 million rounds), disassembled them, and then reloaded them to the original 2,000 ft/s (610 m/s) specification in March 1900.
