Height Over Bore: Understanding Mechanical Offset and Why YOU are missing at close range.

Chris from Regular Guy Training explains his handgun zeroing process, emphasizing starting at 3 yards to establish height over bore and windage before moving to the final zero distance (typically 25 yards). He details how to measure and adjust sights, and the importance of understanding personal shooting tendencies for consistent accuracy.

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 content, featuring Retired Sgt. Maj. Kyle Lamb of Viking Tactics, Inc., focuses on the practical application of the AR-15 platform within the NRA ARC Challenge. It emphasizes fundamental shooting skills such as zeroing, understanding mechanical offset, and utilizing holdovers, crucial for both new and experienced shooters. The discussion highlights how the AR platform's modularity and the ARC Challenge's structure encourage skill development and informed gear choices for all levels of firearm owners.

This video demonstrates the "hammered pairs" drill, a tactical training exercise focused on rapid, accurate fire. The drill involves firing two shots in quick succession, with a slight adjustment to the point of aim for each pair. The emphasis is on delivering effective damage to the target anatomy while maintaining speed, highlighting the importance of understanding "height over bore" for accurate shot placement at varying distances.

This video highlights critical firearm safety failures and explains the concept of 'height over bore.' It demonstrates how the difference in height between a firearm's optic and its barrel affects bullet impact, especially at close ranges. The content emphasizes the importance of understanding this principle and adhering to the four fundamental rules of gun safety to prevent accidents.

This video focuses on the fundamental firearm concept of "Height Over Bore" (HOB). It aims to educate viewers on what HOB is, why it's important in marksmanship and shooting techniques, and how it can affect accuracy. The content likely breaks down the geometry involved, potentially using visual aids to demonstrate how the bore's position relative to the shooter's grip impacts sight alignment and projectile trajectory, especially in dynamic shooting scenarios. This is an instructional video for improving shooting skills.

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.
