The U.S. Navy also contracted with Remington to produce several thousand rolling-block carbines chambered for a reduced load version which was officially produced for use only in carbines, using a shortened .50-70 with a 430-grain (28 g) bullet and 45 grains (2.9 g) of black powder.
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.

The C was to indicate the powder burned "cooler" than traditional Improved Military Rifle (IMR) powders. [4] In 1949, he began acquisition of powder salvaged from disassembled Oerlikon 20mm cannon cartridges. This powder resembled IMR 4350 in appearance, and with a slower burning rate, was initially marketed as "4350 Data", and later as 4831. [5]
The .222 Remington or 5.7×43mm (C.I.P), also known as the triple deuce, triple two, and treble two, is a centerfire rifle cartridge. Introduced in 1950, it was the first commercial rimless .22 (5.56 mm) cartridge made in the United States.
The 7mm Remington Magnum rifle cartridge was introduced as a commercially available round in 1962, [2] along with the new Remington Model 700 bolt-action rifle.It is a member of the belted magnum family that is directly derived from the venerable .375 H&H Magnum. [3]
The amount of recoil the cartridge generates is a step up from the non-magnum .30 caliber (7.62 mm) cartridges. Its recoil is about 30% greater than that of the .30-06 Springfield, [14] which is known as a 'stout' cartridge. With the average load for the .300 Winchester Magnum, the recoil energy is roughly 30 ft lbs.
