Full-power rounds are rifle bullets with a muzzle kinetic energy of more than 2500 joules, and their caliber is generally 7-8 mm (0.).28-0.31 inches), the weight of the warhead is about 9-12 grams (140-180 grains), and the muzzle velocity is about 800-900 meters and seconds (2600-3000 feet and seconds). Full-power bullets were the mainstream rifle cartridges of the First and Second World War periods, and they were represented by the German 792x57mm Mauser bullet, Soviet 762x54mmr Mosin Nagant bomb, American. 30-06 Springfield bullets, etc.
The common characteristics of these types of ammunition are long range, high lethality, and can cause fatal damage to targets at a distance of more than 1,000 meters, which is suitable for long-distance precision shooting. The advantage of full-power bullets is that they can effectively hit enemies from a distance, especially on an open battlefield, and can bring out the maximum power of the rifle. The disadvantages of full-power ammunition are high recoil, large size, and small ammunition carrying capacity, which is not suitable for fully automatic fire and fire suppression at close range.
The recoil of a full-power bullet can affect the shooter's control and accuracy, especially when firing continuously, the muzzle will create a large jump, requiring the shooter to spend more time and effort aiming and adjusting. The large size of the full-power bullet means that the magazine capacity is small, the ammunition carrying volume is small, and the shooter needs to change and replenish the ammunition frequently, reducing the continuity of firepower. The power of the full-power bullet is excessive at close range, resulting in unnecessary waste of resources and ** expansion, and at close range, the enemy's movement speed and reaction time will increase, and the precision shooting advantage of the full-power bullet will be weakened, and it will even be suppressed by the enemy's fire suppression.
Intermediate power rounds are rifle bullets with a muzzle kinetic energy between 1300-2500 joules, and their caliber is generally 5-65 mm (0.)20-0.26 inches), the weight of the warhead is about 3-5 grams (46-77 grains), and the muzzle velocity is about 700-900 m-s (2300-3000 fts). Intermediate power bullets are a new type of rifle cartridge that appeared after World War II, and they are represented by the German 792x33mm Kurz shells, Soviet 762x39mm bullet, 556x45mm NATO shells, etc.
The common characteristics of these munitions are small recoil, small size, and large ammunition carrying capacity, which are suitable for fully automatic shooting and close-range fire suppression. The advantage of the intermediate power bullet is that it can effectively hit enemies at close range, especially on complex battlefields, and can bring out the maximum flexibility of the rifle. The lower recoil of the intermediate power bullet means that the shooter has better control and accuracy, especially when firing continuously, the muzzle jumps less, requiring the shooter to spend less time and effort aiming and adjusting. The small size of the intermediate power bullet means that the magazine capacity is large, the ammunition carrying volume is large, and the shooter does not need to change and replenish ammunition frequently, which improves the continuity of firepower.
The power of the intermediate power bullet is enough at close range, which will not cause waste of resources and ** expansion, and at close range, the enemy's movement speed and reaction time will be reduced, and the fire suppression advantage of the intermediate power bullet will be enhanced, and even the enemy's firepower will be suppressed. The disadvantage of intermediate power projectiles is that the range and lethality are relatively weak, and they are not able to effectively hit the enemy at a distance, and are suitable for accurate shooting at long distances.
The range of the intermediate power projectile is generally between 400-600 meters, beyond this distance, the trajectory will become curved, the muzzle velocity will decrease, the lethality will be weakened, and the shooting accuracy will be reduced. The lethality of intermediate power bullets generally depends on the rolling and rupture of the warhead, rather than the storage and penetration of the warhead, and such lethality will be affected by air resistance and target resistance at long distances, and for the enemy wearing bulletproof equipment, the lethality of intermediate power bullets will be greatly reduced.
