Remington have been producing their legendary Core-Lokt ammunition since 1939 and in true testament to its accuracy and effectiveness it is still being sold around the world today. As the name suggests the bullets copper jacket is “Lokt” to the lead core to deliver massive expansion and maximise weight retention, making it a consistent performer.
Raytrade UK Ltd distribute the Remington branded ammo in the UK in a wide variety of calibres, including .243 Win. This is a popular number in the UK, as it meets the minimum requirements by law, to shoot deer. If a load is selected with a 100-grain bullet, minimum muzzle velocity (MV) of 2450fps and muzzle energy of at least 1750 ft/lbs then it also meets Scottish needs. On test is the Remington .243 Win 100-grain Core-Lokt product, using a Pointed Soft Point (PSP), which is designed to fly faster and flatter than their classic soft point. The rimless, brass case is boxer primed (Large Rifle) so can be reloaded.
The 20-rounds are packed in cardboard boxes and include a plastic separator. Factory figures shows a MV of 2960fps and 1945 ft/lbs of energy. Using a 21.5-inch barrel we got an average MV of 2898fps, an extreme spread (ES) of 76fps and energy was calculated at 1865ft/lbs at the muzzle and 1540ft/lbs at 100 yards. The 100-grain bullet has a ballistic coefficient of 0.356, and when zeroed at 100-yards produced the following figures:
