Maximum Expansion from Lehigh Defense Gel Test

This video compares the terminal ballistics of the 450 Bushmaster and 30-06 Springfield using a ballistic chicken test. The 450 Bushmaster, with a heavier 250-grain bullet, demonstrated significant fragmentation and widespread tissue damage, with large pieces of the projectile and chicken found at considerable distances. The 30-06 Springfield, using a 180-grain bullet, showed good penetration and devastation, passing completely through the ballistic gel after the chicken, indicating a more focused wound channel.

This ballistic gel test compares the penetration and expansion of Federal Punch 29-grain and CCI Velocitor 40-grain .22 LR ammunition. The test, conducted with a Ruger 10/22 Charger, reveals Federal Punch significantly outperforms CCI Velocitor in penetration, reaching 19.5 inches compared to Velocitor's 11.5 inches. Velocitor exhibited expansion, while Punch did not, which is attributed to Punch's design for maximum penetration.

This video details the rigorous bullet testing methodologies employed by Lehigh Defense, featuring insights from Bill Wilson and Mike Cyrus of Wilson Combat. They emphasize the consistency and reliability of testing across various mediums, including ballistic gel, hog cadavers, and water tanks, to validate predictive bullet performance. The process highlights how advanced testing ensures predictable results time after time.

This ballistic gel test compares Sinterfire and Fiocchi Guardian Blue .40 S&W ammunition. Both rounds demonstrated significant fragmentation, creating large wound cavities. The Fiocchi Guardian Blue appeared to produce a slightly larger average wound cavity. Both met FBI penetration standards through denim, with the Sinterfire retaining 57 grains and the Fiocchi retaining 51.9 grains through denim.

This video provides a detailed ballistic gel test of Ammo Inc. Blackline .45 ACP 230gr Hollow Point ammunition, conducted by Buckeye Ballistics. The test evaluates performance through clothing barriers (T-shirt and denim) using a Ruger SR1911 and a Caldwell Chronograph. Key findings include actual velocities, penetration depths, and estimated bullet expansion, offering insights into the ammunition's defensive capabilities.

This video details a ballistic gel test comparing .380 ACP and 9mm Luger Full Metal Jacket (FMJ) ammunition. The test measures projectile velocity and penetration depth, revealing unexpected results where the .380 ACP, specifically a flat-nose FMJ, achieved greater penetration than the 9mm Luger round nose FMJ. The instructor highlights the importance of bullet design in terminal ballistics.

This guide details the dangers of 'thumbing the hammer down' on a loaded firearm, a technique strongly advised against by experts. It emphasizes that this action, which involves pulling the trigger while manually lowering the hammer, carries a high risk of accidental discharge if the thumb slips. The expert instruction highlights safer alternatives like engaging the manual safety for 'cocked and locked' carry or clearing the chamber entirely.

This guide details the advanced technique of hand stippling a 1911 firearm frame for enhanced grip, as demonstrated by a master gunsmith. It covers the precise application of texture using a punch and hammer, followed by meticulous filing to refine the edges. This process requires significant skill and attention to detail for a professional finish.

This guide details the proper technique for cycling the slide on a semi-automatic pistol, specifically the 1911, as explained by Ken Hackathorn. It emphasizes avoiding "gun abuse" by not slamming the slide on an empty chamber, which can cause premature wear. The explanation includes the mechanical reasons behind this, focusing on how the cartridge rim stabilizes the extractor and cushions the slide's action.

Massad Ayoob, a renowned firearms instructor and legal expert, details the critical post-Defensive Gun Use (DGU) protocol. He emphasizes that the most common mistake is failing to immediately call 911 after a DGU, even if no shots were fired. This action is crucial for establishing oneself as the victim complainant in the ensuing legal aftermath.
