The 7mm Remington Bench Rest (7mm BR) is a specialized rifle cartridge primarily used in the sport of benchrest shooting, known for its precision. Developed in the 1970s by Remington, it is essentially a necked-down version of the .308 x 1.5" Barnes cartridge. The 7mm BR typically uses a 7mm (.284 inch) bullet, known for its high ballistic coefficient, providing excellent accuracy and consistency at medium ranges, typically up to 300 yards.
Its casing is shorter and stubbier compared to standard rifle cartridges, which contributes to more consistent internal ballistics and improved accuracy. Benchrest shooters favor this cartridge for its manageable recoil and high precision. The 7mm BR is less common in mainstream hunting or general shooting applications but excels in competitive shooting scenarios.
