Built-In Ballistics, GPS, 6,000-Yard Ranging: Leupold BX-6

This review of the OneLeaf MT1000LRF highlights its performance as a budget-friendly 640 core thermal optic with integrated LRF and ballistic calculator. The instructor praises its ability to hold zero, the accuracy of its ballistic calculator, and the innovative interchangeable lens system, making it a strong recommendation for those entering the thermal market without a high price tag.

This video from Brownells evaluates the utility of smart scopes, specifically the Burris Eliminator 6, for long-range shooting and hunting. The presenters demonstrate how the scope integrates with a smartphone app to provide real-time rangefinding and ballistic solutions, displaying a holdover dot for accurate shots at unknown distances. While acknowledging the technology's effectiveness, particularly for hunters in open country, they also touch on the need for proper zeroing and potential adjustments for windage and elevation.

The Maztek X4 LRF 2K is presented as a 'cheat code' for long-range shooting, integrating laser rangefinding with applied ballistics, motion sensors, and environmental data. It calculates precise holdover adjustments based on user-inputted firearm and ammunition specifications, along with real-time environmental conditions like barometric pressure and wind. The device aims to provide a one-shot hit solution at any distance, simplifying complex ballistic calculations for shooters of varying experience levels.

The Maztech X4-LRF 2K is a sophisticated laser rangefinder designed to act as a 'cheat code' for long-range shooting. It integrates applied ballistics, motion sensors, and environmental data (barometric pressure, wind) to calculate precise holdover adjustments for any target. The device is also night vision compatible and made in the USA, offering unique value at its price point. While it simplifies long-range shooting significantly, potential buyers should consider its longer form factor and the initial sighting-in process which can be challenging in bright daylight.

This review of the AGM Rattler V3 LRF 35-640 thermal optic highlights its features, performance, and reliability. The reviewer, Kyle from Four Mile Ranch, details the optic's V3 generation, integrated LRF, 35mm objective lens, 640 core, and sub-15mK sensitivity. He demonstrates its ease of zeroing, the effectiveness of its onboard ballistic calculator, and its user-friendly interface. The review also touches on its durability over four months of use and its compatibility with Apple computers for firmware updates.

The DNT Hound is a compact thermal monocular that integrates a laser rangefinder and an onboard ballistic calculator. It offers impressive thermal performance with a 640 core and 35mm lens, capable of distinguishing details in various environments. The ballistic calculator provides accurate holdovers in MRAD or MOA, making it a valuable tool for hunters and long-range shooters, especially when paired with non-smart optics. While it excels in functionality, Mac users may encounter data transfer limitations.

This video details the comprehensive manufacturing process of brass rifle casings by Peterson Cartridge. It covers the transformation of raw brass cups through multiple drawing, annealing, washing, heading, trimming, and tapering stages. The process emphasizes precision, quality control through extensive automated and manual inspection, and specialized treatments like neck re-annealing and anti-tarnish coating to ensure match-grade performance.

This guide details essential brass preparation steps beyond basic decapping and sizing for improved reloading accuracy. It covers cleaning, primer pocket uniforming, neck chamfering and deburring, and neck brushing. The video emphasizes that even new brass can benefit from these processes to ensure consistent bullet seating and optimal performance. The presenter, F-class John from Ultimate Reloader, highlights chamfering and deburring as critical steps that should not be skipped, regardless of time constraints.

This video debunks the myth that solid copper bullets require extremely high velocities for effective hunting performance. Through ballistics gel testing and analysis of 7 PRC loads using Barnes TTSX and LRX bullets, Gavin Gear demonstrates excellent expansion and weight retention across a wide velocity range, including lower velocities equivalent to longer ranges. The testing highlights the versatility and effectiveness of modern monolithic copper projectiles for various hunting scenarios and legal requirements.

This video details extreme pressure testing of the 6mm ARC cartridge using both a bolt-action rifle and an AR-15 platform. The experiment pushes the limits of Alpha Munitions brass with 8208 XBR powder, achieving velocities exceeding factory specifications and even 6 Creedmoor. The testing culminates in destructive attempts using a fast-burning pistol powder in an AR-15, demonstrating the significant forces involved and the potential for catastrophic failure. The presenter, Gavin Gear, emphasizes that these tests are for research only and should not be replicated due to extreme danger.
