The original performance of the .276 Enfield fired from the Pattern 13 rifle was 2785 fps with a 165 grain bullet, accomplished with 49.3 grains of cordite. This compares pretty favorably with the 2940 fps. achieved by the 160 grain factory load for the 7mm Remington Magnum and 2860 fps. attained by the 7X64 with the 175 grain bullet, both using modern propellants.

Much better performance on the part of the Enfield cartridge could also be anticipated using modern double base powders.

The notoriously hot burning single base propellant cordite made barrel erosion ferocious and more or less doomed the cartridge before it had even been thoroughly tested, even without the intervention of World War I.
