When shooting at a target 100 yards away, a 1 MOA group is a circle of approximately 1.047 inch diameter, [8] roughly the size of a dollar coin.
For example, a rifle capable of firing a ½ or 0.5 MOA (approximately 0.5 inch center to center of the two holes furthest apart) 5-round group (often referred to as "grouping") at 100 yards will theoretically fire a 12.5 inch group at 2,500 yards (0.5 × 2,500/100 = 12.5). Unless the group is centered perfectly on the target at 100 yards, the ...
Groups for rifles are traditionally shot at either 100 meters or 100 yards (91 m). At 100 yd a minute of arc equals 1.047 inches (26.6 mm), and the one MOA group (approximately 1/3 or 0.3 mil) is a traditional benchmark of accuracy. Handguns are generally used at closer ranges, and are tested for accuracy at their intended range of use.
For reference a 1 MOA circle at 100 yd (91 m) has a diameter of 1.047 in (2.7 cm), 3 in (7.6 cm) at 100 yd (91 m) equals 2.9 MOA, and 5 in (12.7 cm) at 100 yd (91 m) equals 4.8 MOA In summary the accuracy standards of the Gewehr 98 and most other service rifles used in World War I and later were similar.
For 5-shot groups, based on 95% confidence, a rifle that normally shoots 1 MOA can be expected to shoot groups between 0.58 MOA and 1.47 MOA, although the majority of these groups will be under 1 MOA. What this means in practice is if a rifle that shoots 1-inch groups on average at 100 yards shoots a group measuring 0.7 inches followed by a ...
Changes to the rifle include cutting back the fixed stock and integrating a folding adjustable stock, a Desert Tan finish color, and a front loading quick change barrel for caliber change. As of 2011, the only barrel and caliber offered was a 24.5 in (620 mm) fluted barrel with a 1:10" right hand twist chambered for .338 Lapua Magnum. [5] [6] [7]
