How Deadly Are Colibri Bullets?

This video provides a detailed review of Frontier's FR262 77gr OTM ammunition, a budget clone of the MK262 load. The reviewer tested it across five different AR-15 barrels, noting significant velocity variation between lots and individual shots, leading to poor extreme spreads and standard deviations in most cases. While some groups were decent, many exhibited flyers and inconsistent performance, particularly in shorter barrels. The FR262 generally achieved high velocities but struggled with accuracy compared to premium loads.

This video from Yee Yee Life tests the penetration capabilities of various firearms against drywall, ranging from a .22LR to a .50 BMG. The host, Parker, demonstrates how many sheets of drywall each caliber can penetrate, providing a visual comparison of their stopping power in a simulated home environment. The experiment highlights significant differences in projectile energy and effectiveness across calibers.

This video provides an expert-level analysis of Hornady's 6mm ARC 80gr ELD-VT ammunition, tested on a Seekins DMR rifle. The instructor, a specialized precision rifle content creator, details the testing methodology, including chronograph readings, group size analysis using Ballistic-X, and long-range performance evaluation. The ammunition is deemed effective for coyote hunting within 400 yards, delivering consistent sub-MOA accuracy in a gas gun platform.

This video tests the performance of 1-karat diamond-tipped .45 ACP rounds fired from a 1911. The tests included a water jug penetration and a ballistics gelatin test. The diamond-tipped rounds, similar to FMJ, did not exhibit expansion and passed through both water jugs and the gelatin block cleanly, suggesting potential underperformance compared to traditional hollow points in this specific configuration. The presenter questions the effectiveness of .45 ACP hollow points in general based on these results.

This video explores the performance of .30-06 ammunition, specifically focusing on the .30-06 Accelerator sabot round and comparing it to standard Full Metal Jacket (FMJ) and Hornady CX hunting rounds. The presenter conducts ballistics gel tests to demonstrate penetration differences, aiming to explain discrepancies in the Charlie Kirk case. The .30-06 Accelerator shows significantly less penetration, consistent with its design as a small .22 caliber bullet fired at high velocity, often resulting in fragmentation and no exit wound. Standard FMJ rounds exhibit much deeper penetration, while the expanding Hornady CX offers a balance.

This video explores seven ultra-compact revolvers that push the limits of size reduction while maintaining functionality. It highlights historical breakthroughs like the Smith & Wesson Model 1 and Colt New Line, alongside modern examples such as the North American Arms Mini Revolver in .22 Magnum, emphasizing their roles as reliable backup or last-ditch defensive tools.

This video provides an expert-level comparison between the .44 Magnum and .50 Action Express calibers, featuring a Magnum Research Desert Eagle and a Ruger Super Redhawk. The host, demonstrating high authority, conducts a series of tests including penetration through lumber, steel, sand, and concrete, followed by ballistic gel testing with hollow-point rounds. The analysis highlights differences in muzzle energy, penetration, and wound channel, ultimately questioning the cost-to-performance ratio of the .50 AE.

This video provides an in-depth, experimental comparison between .223 Remington and 5.56x45mm NATO cartridges, utilizing a chronograph and various barrier materials. The host, demonstrating high expertise through empirical testing, reveals significant performance differences, particularly in barrier penetration, with 5.56x45mm NATO generally outperforming .223 Remington.

This video from Banana Ballistics explores the surprising lethality of "less lethal" shotgun ammunition. Through rigorous testing with ballistic gel and plywood, the host demonstrates that rounds like bean bags and high-velocity .410 rubber buckshot can cause significant damage, challenging the common perception of these rounds as entirely non-lethal. The testing highlights the importance of understanding ammunition performance beyond its intended classification.

This video provides an objective comparison of 9mm Luger, .40 S&W, and .45 ACP calibers through a series of rigorous tests including lumber, sand, concrete, and ballistics gel. The host, leveraging specialized equipment like a Garmin Xero C1 Pro chronograph and digital calipers, presents data on velocity, penetration, and expansion. While .40 S&W showed competitive performance in some tests, the analysis concludes with a preference for 9mm due to its higher capacity and lower recoil, highlighting the importance of practical considerations beyond raw ballistics.
