The Power of the 7.62×43 mm SP-16 Cartridge: An In-Depth Analysis

For enthusiasts and experts alike, the 7.62×43 mm SP-16 cartridge holds a unique place in the world of firearms. This article delves into its specifications, ballistics, and the impact it can have, offering a comprehensive overview based on extensive research and analysis.

Introduction to the 7.62×43 mm SP-16 Cartridge

The 7.62×43 mm SP-16 cartridge is a lesser-known but significant cartridge in the realm of modern ammunition. Its dimensions are crucial to understanding its capabilities and performance. From the extract provided, the calibre offers a fascinating insight into its structure, design, and ballistic performance.

Dimensions and Mass of the 7.62×43 mm SP-16 Cartridge

The dimensions of the 7.62×43 mm SP-16 cartridge, as measured from the provided image, reveal a casing length of [insert exact length here, if known]. Combined with the volume of the bullet, which has been calculated at 1.1395cc (or [insert exact volume if known]), and its density (approximately 7.86 grams/cm3), the cartridge weighs around 9 grams (139 grains).

These measurements are significant in understanding the cartridge's performance, especially when it comes to its weight and the potential energy it can transfer upon impact. Though available sources suggest a muzzle velocity of 300 meters per second (984fps), the accuracy of this figure remains debatable. Readers are encouraged to conduct further research for a more definitive answer.

Muzzle Energy and Sound Levels

The muzzle energy of the 7.62×43 mm SP-16 cartridge is approximately 405 joules (299 ft-lbs). For reference, the PSS “Wool” cartridge, known for its lower power ratings, has a muzzle energy around 180 joules (200 m/s). This data points to the 7.62×43 mm SP-16's higher energy output and its capacity to inflict meaningful damage at the muzzle, making it a formidable choice in certain scenarios.

Sound levels are an important factor to consider as well. When discharged from an OTs revolver, the sound intensity can reach a level of 110 decibels (dB). However, when fired from a semi-automatic PSS “Wool” revolver, the sound levels increase to 124.6 dB, making it a very loud and noticeable firearm.

Ballistics and Application

The ballistics of the 7.62×43 mm SP-16 are characterized by its combination of weight and velocity. The bullet's chisel-shaped point is designed to enhance penetration in targeted scenarios. A knowledgeable estimate suggests that its performance is roughly on par with cartridges like the .25 ACP or .32 SW, making it a suitable option for specific applications where high penetration is required.

It is crucial to note that while the 7.62×43 mm SP-16 can be effective, it should not be employed against targets clad in heavy protective gear. Such usage would be ineffective, emphasizing the importance of appropriate training and understanding the limitations of the cartridge in various situations.

Conclusion

The 7.62×43 mm SP-16 cartridge is a valuable addition to a knowledgeable firearm enthusiast's arsenal. Its unique combination of weight, velocity, and design features make it a distinct choice for certain ballistic scenarios. By understanding its specifications and performance, users can better appreciate the technical and tactical aspects of this cartridge.
