TheYankeeMarshal, an established firearms community commentator, analyzes the potential risks of a national lead ban for ammunition manufacturers. He advocates for a proactive transition to solid copper ammunition, citing its excellent performance for hunting and self-defense, and a minimal cost increase of 1-1.2 cents per round. This strategic shift could prevent future shortages and price hikes.
The self-defense ammunition landscape is rapidly evolving beyond traditional hollow points, with new technologies emerging to address safety, legality, and performance. In 2025, options like Expanding Full Metal Jacket (EFMJ), frangible, and solid copper rounds offer alternatives, each with unique benefits and considerations. Shooters are encouraged to prioritize reliability through testing, understand local laws, and consider their specific environment and needs when selecting ammunition.
This video provides a detailed ballistics test of Liberty Ammunition's Civil Defense .40 S&W rounds, conducted by a firearms instructor. The testing includes velocity measurements from two Glock pistols (Glock 27 with a 3.5-inch barrel and Glock 22 with a 4.5-inch barrel) and extensive gel block penetration and fragmentation analysis. The instructor notes the ammunition's high velocity, extreme fragmentation, and consistent performance, while also expressing a personal reservation about its lightweight nature for self-defense.
This guide outlines the advanced manufacturing processes at the new Lehigh Defense facility, focusing on their CNC-machined solid copper projectiles. It details production capacity, quality control, and the specific technologies behind their Controlled Chaos and Xtreme Defense bullet designs, highlighting their application in cartridges like 300 HAM'R and 300 Blackout. The information is presented with high authority from industry founders and manufacturing experts.
The Yankee Marshal argues against the common fear of solid copper ammunition over-penetrating in self-defense scenarios. He asserts that high-penetrating rounds are actually safer because they are more effective, increasing the likelihood of stopping a threat with fewer shots, thereby reducing the chance of missing and hitting bystanders. The video emphasizes accuracy and effectiveness over concerns about over-penetration, particularly with handgun rounds.
This video identifies and discusses what the creator deems the "WORST Gun Product of 2017." The description clarifies that the ammunition in question is not hollow point but solid copper, likely round ball. The content appears to be a critical review of a firearm-related product from the gun industry. The creator also provides links to their Amazon shop, Patreon, and merchandise, along with social media channels and contact information.
This video features Edwin Sarkissian conducting a destructive ballistics test comparing various handgun calibers and ammunition types against one-inch thick copper plates. The experiment highlights the penetration capabilities of specialized rounds like Underwood's 9mm and .500 S&W Magnum Xtreme Penetrator compared to standard lead ammunition. The results demonstrate significant differences in performance, with the .500 S&W Magnum Xtreme Penetrator causing substantial deformation to the copper plate.
