Can bullets actually SPEED UP?

This video demonstrates the impact of barrel length on muzzle velocity using .38 Special ammunition. A 1.8-inch barrel Ruger LCR and a 6-inch barrel Ruger GP100 were tested. The results show a significant velocity difference between the two barrel lengths, highlighting how barrel length affects projectile speed.

This guide explains how to accurately measure AR-15 barrel length, which is crucial for understanding its impact on muzzle velocity, terminal performance, and legal classifications. Barrel length is measured from the closed bolt face to the muzzle crown, excluding muzzle devices unless permanently attached. Understanding these measurements is key for informed AR-15 builds and legal compliance.

This video details a test comparing the accuracy of 70-grain Barnes TSX and Hornady GMX bullets in .223 Remington, using Vitavore N540 and IMR8208 XBR powders. The primary focus is to evaluate how barrel condition (dirty vs. clean) affects bullet performance, with detailed measurements of group size and velocity provided for each combination. The instructor, Johnny, demonstrates a methodical approach to reloading and shooting, highlighting the significant impact of copper fouling on velocity and accuracy.

This guide details how to test propellant temperature sensitivity, a crucial factor for consistent long-range accuracy. It emphasizes using a reliable chronograph and testing ammunition across a wide temperature range, from cold to hot conditions. The process involves calculating the muzzle velocity change per degree Fahrenheit to understand how temperature fluctuations affect performance, enabling shooters to account for these variations in their ballistic solutions.

This video from Brownells, featuring Caleb, explores the optimal zero distances for an AR-15, primarily for competition use. It analyzes four common zero distances: 25, 36, 50, and 100 yards, detailing their impact zones on an IPSC A-zone target at various ranges. The instructor emphasizes that the 'best' zero is dependent on the intended use of the firearm and the optic employed, recommending the 100-yard zero as a versatile option for experienced shooters, while suggesting 36 or 50 yards for those using red dots or LPVOs respectively, especially for closer engagements.

This video tests the ballistic resistance of a 1kg rubber mallet against various calibers of ammunition, from .22 LR to .308 Winchester. The mallet demonstrates significant resistance, absorbing or deflecting most rounds, but is ultimately penetrated by the .308. The test highlights the surprising durability of the rubber mallet against firearm projectiles.

This video from TA Targets details an unusual warranty claim involving a steel target with a large penetration hole. The manufacturer's representative, demonstrating high expertise in ballistics and steel properties, analyzes the damage. They conclude that the hole was likely caused by a .50 BMG Mk 211 Mod 0 (Raufoss) round, not the customer's claimed .300 Win Mag, despite the customer's assertion. TA Targets ultimately replaced the target as a gesture of customer support, highlighting their commitment to service even when the damage isn't a manufacturing defect.

This video demonstrates a rapid-fire drill on the TA Targets Phoenix Plate Rack using a PACT Club Timer III. The shooter, exhibiting high authority and expertise, successfully engages all six AR550 steel plates with a handgun. The drill emphasizes clean draw from concealment and high accuracy during rapid fire, showcasing proficient firearm handling.

This video demonstrates a head-to-head competition using the TA Targets Competition Dueling Tree. Two shooters utilize semi-automatic handguns to rapidly flip six reactive steel paddles, showcasing speed and accuracy in a dynamic drill. The drill emphasizes high-speed target transitions and proficient use of modern optics, as demonstrated by experienced shooters on an outdoor range.

This guide, from TA Targets, details the setup and deployment of 'backpack guns' as a supplement to a primary handgun. It emphasizes the 'gray man' philosophy for concealment, comparing draw times between handguns and rifles, and showcases specific builds like a 10.3-inch 5.56 AR pistol and a Veritas Tactical .300 Blackout SBR. The instruction highlights the importance of realistic range training with your chosen setup.
