发帖数: 5546 | 1 1）朋友的AK47， elevation需要往低调5MOA, 可以用专用工具调前瞄对吧？
windage需要往左调3－4MOA,咋整？是不是前准星装歪了？
2）朋友买了Aimpoint PRO， 请推荐个rail mount.
AK的缺口不好用，还是觇孔快。可惜AK的后瞄没办法靠近眼睛，只能用缺口。 |

发帖数: 1943 | 3 在什么天气条件下首发命中多大的目标？
你们公司的系统没看到有什么全场风速的测量系统，如果按宣传片里手动输入的射手位
风力值，除非你要打benchrest，不然多普勒测量的弹道精确下落在远距离和10块钱一
个的Android或者Iphone弹道计算程序没有本质区别。这个东西能打多少中远程首发命
中率，普通步枪也能打多少，算上输入后到射击前出现风变需要校正的情况，普通枪因
为能由射手自己压windage可能首发命中率还高一点。
至于补中，这在一个需要重新花时间Tag还没有reticle的系统里本身就非常不靠谱
整个系统的构想和实施，现阶段看来就是个高价靶场玩具而已
另外一般步枪打组是走瞄准点，在打组过程中不作调整的。这一点来说每发也都是首发 |

发帖数: 35 | 4 还记得在Top Shot Season 2 里有一集是 the 1000 Yard Shot. Shoot at a 30-inch
target from 1,000 yards; maximum 5 minutes and 15 rounds per player. using
Barrett M82A1 rifle (.50 BMG). 当时是45mi的侧风。选手里George Reinas 是
sniper出身, 所以其他的选手都是看弹着点再做修正,只有George Reinas 是一发命
中/31秒。不过他的时间并不是最快的。最快的是Jaime Franks,4发30秒。其他选手的
调整过程不过是用取样的办法来去猜,或者说是去试真正的弹着点，而George
Reinas的训练让他能够算出来。
不过好象Poorguy 和HP 之间的交流上的确有Misunderstanding. 首先，group的概念：
在打同一组group的时候，point of aim(POA)是不变的，而且镜子的设置也是不变的
。弹着点分布可以告诉我们2个信息：弹着点的中心位置，以及弹着点的散布范围。

请教各位大牛几个问题
1. Troy 的前后瞄可以调整elevation/windage么？看了半天没找到在哪
2. 清洁，润滑 工具应该准备哪些？第一次打之前需要润滑么？ 想要买好了再去靶场
试枪
3. 需要zero么？怎么做？ |

发帖数: 326 | 6 可以，前瞄其实像个螺丝一样，不过被一个小卡笋锁住。需要用小螺丝刀或者专用工具
向下压住卡笋然后左右旋转调整elevation。后瞄的侧面同样有个像拨轮的东西，用
coin可以旋转来调节windage。 |

发帖数: 1943 | 10 如果说24和26寸管区别不太大我还信，但是20寸管距离一远差距相当明显。
昨天春寒料峭50F，在靶场被10-20mph的多变风速耍的团团转，一千码用FGMM个人感觉
24比26寸稍微难打了一点，elevation差距不大，但是windage24寸要比26寸明显扩散难
调节。而远射靠的就是Windage吃饭
20寸这种天气可以回去睡，16寸连出门都不用出
至于高精度步枪端着打，我觉得有点浪费子弹和体力的意思 |

发帖数: 5546 | 11 一伙人刚回来，更新一下，我的Weatherby 30-06猎枪加布什那尔3－9x镜子，1000码：
我把Elevation Up拧到头，再hold over，xs7帮我观靶，第一发第二发之后，windage
向左拧17clicks, hold over靶子上边大约20inch的地方(因为是仰角，故意少hold了点
。)，第三发命中！ xs7上我观靶，他上来第一发命中！ 无压力
主要是新手第一次用自己的猎枪打中1000码，很开心。 见笑见笑。
xs7和枪老板之前把R700调好了，后面就很容易，xs7基本每发都命中1000码的人型靶(
我不知道有多大)，主要今天运气好，我测了下射手位置，风不大也就5mph左右. |

发帖数: 5546 | 14 设计这个Z的目的是，25米距离够近，新手也很容易Zero；这个距离也很标准，战时也
容易找到合适的靶场。但距离近一些误差比较不容易体现，所以建议最好在50米，100
米验证一下，特别是windage. |

发帖数: 5546 | 15 随便假设一个，比如目标身高1.78米＝5.8ft= 70inches（请注意：随便放狗搜的图，
举个例子方便讨论，本人及众网友没有任何暴力倾向）
1个密位约等于3.6inches @100yards； 0.1米@100米，1米@1000米。
要是SFP镜子要读下说明书，举个例子Vortex Viper 6.5-20x44在14倍：
Mil Dot reticle is useful for helping estimate range,windage and bullet hold
-over. Good for long distance shooters and hunters who need the ranging
ability. The Mil Dot subtensions are accurate at 14x.

akula (大鲨鱼 / 达不溜博士) 于 (Sun Apr 21 01:35:13 2013, 美东) 提到:
因为最近研究狙击步枪，所以有关的资料都随便看看。
发现对于常见的223或者308口径来说，20寸枪管和24寸的初速区别并不大。
根据我查到的和听说的，308的20寸管的初速比24寸管也就小100fps左右，而典型的168
格令的308的弹（比如Federal Gold Match 168gr HPBT），在从muzzle到100码距离的
时候，速度差不多就衰减了200fps了，也就是说，即使用24寸管，那么弹头飞到100码
的时候，速度已经小于20寸管的枪口初速了。
这样说来，20寸管的枪口初速，其实大概相当于24寸管的弹头飞到50码左右的速度，肯
定高于飞到100码的速度。那么，24寸管的308的有效射程，应该比20寸管的有效射程，
也就不过增加区区50码左右，撑死了不超过100码。
如果24寸管的308可以打到1000码，那么20寸管的打900码应该一点问题都没有。

都很准，退到４０码附近才有比较明显的区别．而且我觉得主要不是枪，而是９２上面
的前瞄太暗了，无法聚焦．pattern应该是偏下，大概２５码１－２寸的偏差，略微有
一点点偏左．后来ky windage瞄右上（挂钩低一点的位置）打的基本都在中间一拳的范围
