This video explores the complexities of high-pressure and hybrid ammunition, featuring insights from ammunition designer Jesse (Boondock Battle Station). It debunks the notion of 'easy plug-and-play' performance gains, highlighting manufacturing challenges, potential weapon system degradation, and the need for redesigned components. The discussion emphasizes that current commercial high-pressure loads offer modest velocity increases, and the true potential lies in future weapon system development for smaller platforms.

This video demonstrates the dangerous consequences of firing incorrect ammunition in a .308 Winchester rifle. The host, exhibiting high-level expertise, tests .243 Winchester, .260 Remington, and 7mm-08 Remington rounds, highlighting issues like fire-forming brass, extreme inaccuracy, tumbling projectiles, and significantly reduced velocity due to gas blow-by. While technically possible in a dire emergency, the experiment concludes that using the wrong caliber is ineffective and hazardous.

This video tests the lethality and penetration of fishing weights fired from a shotgun. The experiment uses a one-ounce fishing weight, testing its impact on a water jug for energy, a bulletproof vest for lethality, a paper target for accuracy, and a helmet for armor penetration. The results indicate that fishing weights fired from a shotgun are lethal and can cause significant damage.

This video tests the lethality of Nerf darts fired from a shotgun. While the Nerf dart demonstrated significant energy, cracking a soda bottle and hitting near the center of a paper target, it did not penetrate the target completely. The test also observed unburnt powder exiting the barrel, indicating potential issues with projectile weight and balance.

This video tests the in-water stability of various commercial .410 bore slugs using a water drop test. It highlights significant differences in projectile flight path and stability upon impact, with some slugs tumbling or flipping, while others maintain a straighter trajectory. The Brenneke slug demonstrated exceptional stability, dropping perfectly straight.

This video from Boondock Ballistician delves into the science behind Open Tip Match (OTM) ammunition, explaining its manufacturing process and impact on accuracy. The instructor highlights how bottom-up manufacturing provides better control over bullet base geometry, crucial for minimizing projectile instability upon exiting the barrel. While OTM rounds are designed for precision, the video also discusses their limitations, such as lower ballistic coefficients and unpredictable drag at transsonic speeds, and emphasizes that for most shooters, the performance difference compared to standard FMJ rounds is negligible.

This video provides an expert-level explanation of ammunition grain weight, detailing its significance for projectile performance. Instructors Kai and Jason break down how grain weight impacts velocity, stability, penetration, and ballistic coefficient across various calibers like 5.56 NATO, 300 Blackout, and 9mm. They emphasize that grain weight is a critical factor for selecting the right ammunition for specific applications, from long-range precision to self-defense scenarios, and how it interacts with barrel twist rates.

This video delves into determining the maximum effective range of firearms by analyzing velocity, energy, and mechanical limitations, a concept taught by Adrian of Sidewinder Concepts. It highlights how the transonic range significantly impacts projectile stability and predictability, emphasizing that while hits can be scored beyond this zone, repeatability decreases. The discussion contrasts high-performance rifles with cartridges like 7.62x39, illustrating how factors like ballistic coefficient and wind greatly influence long-range accuracy and effective terminal energy delivery.

This video details a water drop test conducted on 11 commercial .410 slugs to assess their in-air stability. The test involved dropping slugs into a 14-inch water column and observing their trajectory. Results indicated significant performance differences, with Brenneke and Winchester Super X slugs performing best, while others like Sterling, Federal, and BPS slugs exhibited poor stability, tumbling, or sideways flight.

This video details the experimental testing of custom-made shotgun slugs crafted from deer or antelope antlers. The host, a firearms content creator, demonstrates their performance against various targets, including ice, cardboard, OSB board, and a mannequin equipped with duct tape body armor. The tests reveal poor projectile stability, with slugs tumbling in flight and failing to penetrate the armor, highlighting the limitations of this unconventional ammunition.
