Also known as: .30 Bench Rest, .30 BR Remington, 7.62x47mm

About .30 BR

The .30 Bench Rest, commonly known as .30 BR, originated in the 1970s as a wildcat cartridge designed for precision shooting. Developed from the .308x1.5 inch Barnes, it gained popularity in benchrest shooting due to its superb accuracy. The cartridge was officially standardized by the International Benchrest Shooters organization, emphasizing its precision pedigree.

Technically, the .30 BR typically features a case length of about 1.52 inches, with a shoulder angle that promotes consistent chamber alignment. It operates at moderate pressures, increasing both barrel life and shooting comfort. Reloaders appreciate that the .30 BR has a large case neck, about 0.308 inches in caliber diameter, which allows for secure bullet seating and efficient case capacity use. It generally requires small rifle primers, which aid in ignition consistency.

Ballistically, the .30 BR excels in short to medium-range targets, making it ideal for 100 to 300-yard competitions. It typically uses bullet weights ranging from 110 to 125 grains, offering a balance between velocity and precision. The cartridge can achieve velocities around 2,900 feet per second, depending on bullet weight and powder choice, which provides flat trajectories and impressive accuracy.

For competitive shooters, especially in benchrest and varmint categories, the .30 BR offers unparalleled precision. Reloaders benefit from its efficiency, as it allows for repeated case life due to its design and moderate loading pressures. Additionally, its lesser powder requirements make it a cost-effective choice for those invested in precision shooting disciplines. Overall, the .30 BR remains a revered choice for target shooters seeking ultimate accuracy.
