This video clarifies the differences between M193 Ball and SS109 (Green Tip) ammunition, focusing on their compatibility with different barrel twist rates. It explains that M193 (55 grains) is optimized for a 1:12 twist, while SS109 (62 grains with a steel penetrator) requires a faster 1:7 twist for optimal stabilization and accuracy. The instructor debunks the myth that Green Tip ammunition damages chrome-lined barrels, stating that improper ammunition selection for a given twist rate leads to inaccuracy, not barrel damage.

This AR-15 ammo review highlights the performance differences between various 5.56mm rounds. The Hornady V-Max 55 grain is noted for its fragmentation, while the 62 grain SS109 is deemed suitable for practice due to over-penetration. For defensive use, heavier grains like the 77 grain Sierra Match King and 70 grain Barnes, along with the M855A1 for hydrostatic shock, are recommended.

This video focuses on the ASMR experience of loading AR magazines with New Republic 5.56 NATO 62 Grain SS109 ammunition. The title explicitly mentions 'AR mags' and the caliber '5.56 NATO', along with the specific grain weight and bullet type. The hashtag #gun further confirms the firearm context. While the primary focus is the ASMR aspect, the content inherently relates to firearm accessories and ammunition.

This video demonstrates the principles of designated marksman rifle (DMR) marksmanship, focusing on engaging targets at extended ranges (100-500 meters). It covers proper scope usage, trigger control techniques like the 'squeeze' and 'empty lung' method for breath holding, and the importance of consistency for accurate fire. The instruction emphasizes achieving hits at distances up to half a kilometer using standard ammunition.

This "Stockpile Saturday" video focuses on acquiring ammunition for two distinct firearm calibers: 5.56x45mm SS109 and .410 bore 2 1/2" slugs. The creator highlights a sale from their "favorite online retailer," which offered a 16% discount and free shipping on ammunition. They purchased 800 rounds of the 5.56x45mm and six boxes of Winchester Super X .410 slugs, emphasizing the "buy it cheap, and stack it deep" philosophy for building an ammo stockpile.

The Beretta AR-70/90, Italy's standard service rifle for two decades, evolved from the AR-70 to meet NATO's 5.56mm SS109 ammunition standards. It features STANAG magazine compatibility, a unique detachable carry handle with integrated sights, a bipod, and a grenade launcher capability. The rifle was replaced by the ARX-160 and is now available as parts kits for civilian builds.

This video provides an expert-level comparison of four common 5.56/.223 ammunition types (XM193, SS109, M855, and M855A1) tested for steel plate penetration. Using a custom bolt-action rifle and a MagnetoSpeed chronograph, Banana Ballistics objectively measures velocity and penetration depth, revealing significant differences in performance, especially against hardened AR500 steel. The M855A1 demonstrated superior penetration capabilities in mild steel, while all rounds struggled against AR500.

This review of the HM Defense Stealth 556 upper highlights its unique integral suppressor design, featuring a 9-inch button-rifled barrel with a monoblock machined directly into it. The setup offers a compact form factor suitable for CQB, personal defense, and hunting applications like hog or coyote hunting. The reviewer emphasizes the accuracy and rigidity of HM Defense's barrels, noting the effectiveness of the integrated suppressor and the improved HM Defense Bolt (HMB) for enhanced durability.

This video discusses a potential government action to curb the civilian supply of M855/SS109 "green tip" 5.56x45mm NATO ammunition, referencing an article from The Truth About Guns. It also touches upon the ammunition needs in Ukraine, linking to articles from Euromedia Press and CSIS. The creator promotes various survival and preparedness products, including coffee, solar power solutions, personal protection gear, body armor, eye protection, medical kits, hearing protection, and long-term food storage, suggesting these are relevant for 'SHTF' scenarios.

The Biden administration is reportedly altering the government contract for the Lake City Ammunition Plant, operated by Winchester, to prevent the sale of excess M855 and SS109 (.223/5.56) ammunition to the civilian market. This action is expected to reduce the civilian supply by approximately 30%, potentially driving up ammunition costs and making it more expensive for Americans to shoot their firearms.

This video details the process and results of establishing a 50-yard zero for a combat rifle equipped with an LPVO. The instructor emphasizes that zeroing is rifle, ammunition, and environment-specific, not a universal gospel. The test demonstrates how a 50-yard zero impacts point of aim at extended ranges like 100, 200, 300, and 400 yards, highlighting the need for holdovers or adjustments at greater distances.

This video provides an in-depth look at the Sellier & Bellot rifle ammunition manufacturing process, from raw brass to finished rounds. Expert Larry Vickers and manufacturing specialist Mike Fisher detail critical steps like annealing, case drawing, bullet production, and automated quality control. The process culminates in high-speed loading on the 'Scorpion' machine, producing 160 rounds per minute.
