The article titled "What Is a Practical Zero?" written by Wayne van Zwoll for The Armory Life delves into the process of zeroing a rifle for precise shooting. The piece begins with a historical account of Sir Samuel Baker, a renowned African explorer and hunter, recounting his experiences with Victorian-era rifles, which required precise adjustments for long-distance accuracy. The narrative showcases the advancements and misconceptions in firearm accuracy and sight adjustments over time, noting examples from historical advertisements and shooting practices.
Wayne van Zwoll discusses essential steps for achieving a practical zero in modern rifles, emphasizing the importance of properly mounting a scope and ensuring its stability using tools like a torque wrench. The article advises on bore-sighting and firing precise shots to adjust windage and elevation (W/E) settings accurately. Highlighting the necessity of understanding a rifle's trajectory and potential environmental influences, van Zwoll urges shooters to test their guns across various positions and ranges, recommending a 200-yard zero for most hunting situations to maintain effective point-blank range.
The author explains the role of scope power settings and target size in achieving a reliable zero, particularly in varying field conditions. Citing advice from historical figures like Warren Page, van Zwoll suggests using moderate magnification for practical field use. The article concludes with insights on aiming error due to parallax and the importance of zero verification over time to ensure continued accuracy.
