These are both more energetic by mass than black powder and can produce higher velocities and pressures. Triple Seven is a volumetric substitute for black powder, and due to its higher velocity, it is recommended to reduce the load by 15%. [11] The carbon-based fuel burned in this case is from the sugar family, not from charcoal.
Compared to the 7mm Remington Magnum, top 7mm RUM loads deliver 25% more energy at 300 yards. [citation needed] Such performance demands a price and in this case, that is a large muzzle blast, sharp recoil and short barrel life. [1] The 7mm Ultra Magnum boasts the largest case of any commercial 7mm cartridge.

This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
