This video debunks the myth that lubricating ammunition is beneficial. The host explains that oil on ammunition can lead to dangerous pressure spikes within the firearm due to altered case expansion against the chamber walls. This excess pressure can cause head thrust, damaging bolt lugs, flattening primers, and potentially causing the firearm to over-cycle. The video emphasizes that any feeding or extraction issues should be addressed by fixing the firearm itself, not by altering the ammunition. It advises against lubricating ammunition for any firearm, including for handloaders who should remove case sizing lube.

This video debunks a common misconception about the "M" in US military firearm designations like the M16 and M4. Contrary to popular belief, and despite claims by some gun control proponents online, the "M" does not stand for "military." Instead, Brownells Gun Techs™ Caleb and Steve explain that "M" actually stands for "model," meaning M16 simply refers to Model No. 16. The video also briefly touches on the "AR" in AR-15, clarifying it stands for "Armalite Rifle" and not "assault rifle." This is presented as a myth-busting segment.

Storing an AR-15 with the hammer down (forward) or hammer back (cocked) does not impact spring longevity; springs wear from cycling, not compression. The 'rack safe' military procedure, requiring the hammer forward, is for visual confirmation of an empty chamber and selector position, not firearm preservation. Ultimately, personal preference dictates storage method without affecting the rifle's lifespan.

This review debunks the myth that shooting steel-cased ammunition followed by brass-cased ammunition causes extraction failures in handguns. Through a live-fire test using a CZ P-07, firing 100 rounds of Wolf steel-cased 9mm followed immediately by LAX brass-cased ammunition, zero malfunctions occurred. The speaker, with over 30 years of experience, concludes this myth is invalid for handguns, warning against internet misinformation.
