Videos tagged with Corrosive Ammunition

This video provides an in-depth review of the Zastava ZPAP M72 RPK rifle, highlighting its Yugoslavian/Serbian design origins and improvements over Soviet RPKs. Key features discussed include the 1.5mm receiver thickness, non-chrome lined barrels on original models (contrasted with modern chrome-lined cold hammer-forged barrels from Zastava USA), unique finned barrels for heat dissipation, adjustable sights, and a bolt-hold-open mechanism tied to the follower. The review also covers disassembly and reassembly procedures, offering insights into the rifle's construction and reliability.

This video discusses the potential risks of using modern ammunition in older firearms, specifically mentioning the M1 Garand and a Mosin Nagant. It highlights that while modern ammunition is generally less corrosive than older types, using it in firearms designed for less powerful rounds can still cause damage. The presenter notes that modern 7.62x54R ammunition for the Mosin Nagant is non-corrosive, making it a safer and more convenient option than the original corrosive rounds.

This video explores the impact of modern ammunition on older firearms, specifically a Mosin Nagant. It debunks the myth that all modern ammo is detrimental to vintage guns, highlighting that non-corrosive primers in modern 7.62x54R ammunition can actually reduce maintenance needs compared to older corrosive variants. The presenter demonstrates that using this modern ammo can prevent barrel damage from residue, saving cleaning time.

This video explores the current state and historical significance of the 5.45x39mm caliber and the AK74 platform. The presenter, KLAYCO47, highlights the caliber's excellent shooting characteristics, including soft recoil and flat trajectory, and its historical context as Russia's response to 5.56x45mm. The video discusses the dramatic price fluctuations of AK74s and 5.45x39mm ammunition, particularly during the COVID-19 pandemic, and the current market challenges. It also touches on the availability of new brass-cased 5.45x39mm ammunition from Global Ordinance and promotes the upcoming Kashbash Texas event.

This video explores the 7N6 'poison bullet,' a 5.45x39mm round designed for the AK-74. It details how its steel penetrator core, combined with unique geometry, causes extreme tumbling and yaw on impact, creating a large wound channel without fragmentation, thus technically avoiding classification as a prohibited expanding bullet under the Geneva Conventions. The video contrasts its performance with standard 5.45x39mm and 5.56 NATO rounds using ballistics gelatin and water jug tests, highlighting its effectiveness but also noting its corrosive nature and potential availability/price issues.

This video from Kentucky Ballistics explores whether modern firearms like the AR-15, AK-47, Glock 17, and 1911 can function using black powder. Instructor Scott demonstrates that while these firearms can technically fire black powder rounds, they experience significant reliability issues due to fouling, insufficient energy, and the corrosive nature of the propellant, requiring immediate and extensive cleaning. Chronograph data shows substantially lower velocities compared to modern smokeless powder.

This review of GROM 7.62x39mm ammunition from Poland, imported by Atlantic Firearms, details its performance over 1000 rounds. The ammunition is remanufactured surplus with lead cores, lacquered steel cases, and corrosive Berdan primers. While it proved reliable in standard 16-inch AKM platforms like the WASR-10 and Egyptian Maadi, it exhibited significant issues including failures to fire and stuck cases in short-barreled AKs such as the Riley Defense Krink. The ammo is noted as dirty-burning and corrosive, requiring immediate cleaning after use. Despite its drawbacks, it's considered a viable budget option for compatible firearms.

This review examines the Riley Defense RAK47 'Krink' after 1,695 rounds. The presenter notes initial concerns about premature wear on bolt lugs and the carrier, which were addressed by Riley Defense. A significant issue encountered was a failure to charge after magazine insertion, later diagnosed as a fouled gas block due to running the firearm hard and suppressed. The review also touches on rust concerns potentially linked to corrosive ammunition. Despite initial wear, the firearm's performance stabilized after returning from Riley Defense, with no further advancement in wear observed.

The Yankee Marshal discusses preventing and removing pitting on firearms. He emphasizes keeping guns clean and dry as the primary preventative measure. He also advises against using steel wool on stainless steel firearms due to residue that can cause pitting, recommending synthetic steel wool instead. Proper lubrication and avoiding contaminants are key to maintaining firearm condition.

Instruction from Rob Ski of AK Operators Union, a recognized expert, debunks the myth of constant AK cleaning. He advises cleaning only after 3,000-5,000 rounds for standard use, emphasizing the AK's durability. Special protocols are outlined for corrosive ammunition, and the risks of over-cleaning with steel rods are highlighted.

This video provides an in-depth look at the 5.45x39mm cartridge and AK-74 platform, discussing its current viability as a firearm purchase. It covers ammunition availability, accuracy comparisons to 5.56x45mm, penetration capabilities, maintenance considerations for corrosive ammo, recoil dynamics, and overall system weight. The presenters emphasize the importance of stocking ammunition before purchasing a 5.45x39mm firearm due to potential import restrictions and fluctuating market availability.

This video debunks the myth that chrome-lined barrels are inherently less accurate than unplated or stainless steel alternatives. Steve and Caleb from Brownells explain that modern chrome-lining processes, especially on cold hammer-forged barrels, are highly consistent and do not negatively impact accuracy at typical shooting distances. They highlight the significant durability and corrosion resistance benefits of chrome lining, making it a practical choice for many shooters.
