why do i keep hearing this magic 10yd rule for defense?

This guide, presented by Shortshot Tony, details the easiest method for zeroing a handgun optic using the Tactical Elites Laser Bore Sighter. It emphasizes proper tool selection, installation, and alignment, culminating in a crucial live-fire verification step. The process is designed for efficiency, allowing shooters to get on paper quickly before final adjustments.

This guide details the technique for establishing a 36-yard zero on an AR-15, as demonstrated by experts from Brownells. This zero is favored for its ability to keep bullet impacts tightly stacked from 25 to 250 yards, making it ideal for competition and unknown distance shooting. The process involves bore sighting, firing initial groups, calculating necessary scope adjustments using MOA conversions, and refining the zero for optimal accuracy.

This video provides an expert-level analysis of rifle zeroing strategies, challenging the conventional wisdom of 'Battle Zeros.' The speaker, demonstrating high authority with deep familiarity in tactical shooting theory, advocates for the 100-yard zero due to its flatter trajectory and reduced deviation at critical engagement distances, especially when using modern magnified optics. The content includes detailed ballistic data and critiques common assumptions about target sizes and engagement scenarios.

This video debunks the myth that a 25-yard zero is ineffective. The speaker, demonstrating high authority, explains that a 25-yard zero can provide a point-of-aim, point-of-impact relationship out to 300 yards, making indoor ranges with 25-yard limitations perfectly suitable for achieving a reliable firearm zero.

This guide details the process of sighting in a handgun red dot optic, emphasizing periodic checks and proper zeroing techniques. It covers co-witnessing with iron sights, selecting the correct zero distance and ammunition, making mechanical adjustments, and confirming the zero through practical application. The instruction highlights the importance of a shooter-specific zero that accounts for individual grip and trigger mechanics.

This guide details how to zero firearm optics, emphasizing that the ideal zero depends on the rifle's purpose and engagement distances. It covers common zeroing distances, the physics of bullet trajectory relative to the optic, and considerations for magnified optics with BDC reticles. Instruction from a firearms expert highlights the importance of understanding height over bore and choosing a zero that provides a practical point of impact for intended use.

This guide details how to properly zero a red dot sight on a 9mm handgun, based on expert instruction. It emphasizes understanding mechanical offset and ballistic trajectory. The video advises against zeroing at very close distances like 5 yards, recommending a 15-yard zero for 9mm handguns as it provides a more predictable point of impact at common engagement distances, typically around 50 yards.

This guide details the unique top-loading process for the Kel-Tec P50 pistol using stripper clips, as demonstrated by Shortshot Tony. It covers loading 20 rounds of 5.7x28mm ammunition and highlights the firearm's exceptionally lightweight design and minimal recoil during firing, offering a practical overview for potential users.

This video from SHORTSHOT TONY provides practical advice on defensive target selection, emphasizing aiming for the pelvic girdle rather than the head or center mass when facing threats potentially wearing body armor. The instructor, identified as a firearms enthusiast with practical shooting experience, humorously but directly explains the tactical advantage of targeting the pelvis to immobilize an opponent. The demonstration utilizes a 2011-style pistol equipped with a red dot optic.

SHORTSHOT TONY, an experienced tactical content creator, explains the proper use of red dot sights and iron sights. He emphasizes that co-witnessing is for backup purposes, not simultaneous aiming, and that red dots are parallax-free. Tony advises against aligning the red dot with irons for every shot, suggesting it's a misuse of the optic's capabilities and potentially a waste of money if not utilized correctly.
