Remington Core-Lokt was the first and original controlled expansion bullet, and remains the standard of big-game bullet performance. Its level of reliability is only exceeded by the amount of game it has taken over the years. Remington has been the leading innovator in modern centerfire cartridges - not only the bullets, but also Kleanbore, the first non-corrosive primers; the brass historically preferred by serious reloaders, and best blends of the finest powders available.
Express Core-Lokt Pointed Soft Point Bullet
Unquestionably the best all-around choice for modern big-game hunting. By adding a sleeker nose profile and higher ballistic coefficient to the dependable, controlled expansion characteristics of the Core-Lokt soft point, it combines exceptional bullet penetration and performance with flatter trajectory and higher down-range velocity and energy. The result is reliable expansion of almost 2x caliber diameter at virtually all ranges and practical velocities.

The 7X57mm Mauser (7mm Mauser, 275 Rigby) was developed by Peter Paul Mauser in 1892, based on his 8X57mm case necked down. It was quickly adopted by Spain, later by Mexico, and was purchased in large quantities by the Boer Republics in South Africa. Thus America faced the 7x57 in the Spanish-American War and the British faced it in the Second Boer War. Both were impressed by its range and accuracy and it became a popular sporting cartridge in the English-speaking world. In 1899 John Rigby renamed it 275 Rigby for the British market. Early hunters such as W.D.M. Bell and Jim Corbett used it for very large game, but it's really ideal for deer-sized game and was a favorite of Jack and Eleanor O'Connor. In America it has been largely replaced by the ballistically similar 7mm-08, but it retains a small but loyal following. Current factory loads are mild because of older (pre-98) Mausers still in use, with a 140-grain bullet at about 2680 fps standard. —
