This video provides a practical, field-expedient method for zeroing a Ballistic Drop Compensator (BDC) turret on a rifle, as demonstrated by LRU instructor Ian Miner. The tutorial focuses on a quick and effective technique for shooters to establish their BDC zero in a field environment, which is crucial for accurate long-range shooting. The video also promotes the Gunwerks YouTube channel for more content on long shots, shooting tips, DIY projects, and ballistics, and mentions their free Revic Ops Ballistic App.
This video challenges the common practice of zeroing Ballistic Drop Compensator (BDC) reticles at 100 yards. The presenter argues that due to variations in altitude, ammunition, barrel, and other environmental factors, a 100-yard zero often doesn't accurately match the BDC's intended trajectory. The video suggests this is why certain optic placements, like ACOGs on short-barreled firearms, can still be effectively utilized with their BDC reticles, and explains why alternative zero distances (36, 50, 25 yards) can also be inconsistent. The content aims to provide a more nuanced understanding of BDC zeroing for practical application.
