SVD的精度手册上就标了个≤ 2 MOA ,怎么85"改进"成超过2MOA了。而且军用狙击枪2MOA是不太好,但毕竟要求不是运动用枪那么高,还要平衡复杂环境的使用维护保养等方面。
Contrary to popular belief, sniper rifles are not necessarily characterised by exceptional accuracy, especially when compared to civilian sporting rifles, though they nearly always match or exceed the capabilities of other rifles in the military and police categories. A military-issue battle rifle or assault rifle is usually capable of between 3 and 6 minute of arc (MOA) accuracy. A standard-issue military sniper rifle is typically capable of 0.5 to 2 MOA accuracy, with a police sniper rifle capable of 0.25 to 1.5 MOA accuracy. For comparison, a competition target rifle may be capable of accuracy levels up to 0.1 MOA.
The United States military standards call for 1 MOA accuracy from a standard issue sniper rifle since accuracy is sacrificed in favor of low cost and reliability in harsh environments, as well as ease of operation and maintenance. This level of accuracy roughly translates into a variance in the bullet's point of impact of 8 inches at 800 yards, which is considered sufficient to ensure a high probability of hitting a human shape at that distance.
还有按下图1MOA在800米20CM散布直径,3MOA在800米40CM散布直径。那个2MOA的"800米射击弹着点跟目标误差最大可能达到20CM"怎么来得呢?那应该是3MOA的数吧。
