This video from Warrior Poet Society explains how temperature significantly impacts long-range rifle accuracy. Instructor John Lovell details two primary mechanisms: changes in air density, which affect bullet flight, and alterations to the powder's burn rate, influencing projectile velocity and energy. Understanding these variables is crucial for consistent performance at extended distances.

This video discusses critical considerations for long-range shooting, focusing on elevation adjustments. It explains how to use ballistic calculators, dope cards, or apps like Applied Ballistics to determine holds or dial in corrections based on range. The instructor also highlights the significant impact of temperature on both air density and powder burn rate, affecting bullet trajectory and velocity.

This video demonstrates the burn rates of different firearm powders, including black powder, H110, Trail Boss, and IMR 4350, when burned uncontained in the open. The presenter highlights significant differences in burn speed, with black powder being the most rapid and volatile, followed by pistol powders like Trail Boss, and then slower rifle powders like H110 and IMR 4350. The experiment serves as a visual comparison of powder characteristics outside of a firearm's pressure environment.

This video explains how powder burn rate and barrel length significantly impact bullet velocity in reloading. Slower burning powders like Varget perform better in longer barrels (24 inches) by allowing more time for pressure to build, while faster burning powders like BLC-2 can yield better velocities in shorter barrels (16 inches) due to efficient pressure generation.

This guide details how to optimize pistol compensator performance, emphasizing the critical interplay between firearm, ammunition, and gunpowder choice. It highlights that lighter bullets and slow-burning powders generate more gas for effective compensation. The guide also covers practical considerations like tuning recoil springs for reliability and the pros and cons of using carry comps, drawing on expert insights from The Humble Marksman.

This video analyzes Eugene's sabotage plan in the Walking Dead finale, where he caused enemy firearms to explode. The instructor, with over 10 years of reloading experience, explains that the most plausible method was using the wrong powder burn rate. By filling rifle cartridges with fast-burning pistol powder like Red Dot, the pressure would build too rapidly within the shorter barrel, causing catastrophic failure at the chamber, consistent with the visual evidence.

Nosler introduces its new SSA (Semi-Auto Specific Ammunition) line, engineered to optimize reliability and performance in semi-automatic rifles. This ammunition is specifically tuned with adjusted powder burn rates, charges, and bullet weights to ensure correct bolt velocity, a critical factor for consistent cycling. The SSA line offers various bullet types, including varmint, hunting, defense, and match options, across popular calibers like 5.56 NATO, 6.8 SPC, 300 Blackout, .308 Winchester, and .30-06 Springfield, addressing common feeding and function issues encountered with traditional hunting ammunition in semi-auto platforms.
