镜子每格调节是固定角度的，在100yds上是0.25，你现在靶子在6yds上，那么画个三角形算一下，在6yds上就是 ...

谢谢师兄，画了相似三角形，确实是你的算法正确。

换个枪把，这是个给小朋友用的小号枪。便宜货，我从来没听说过这个。
弹簧折管枪很不好打，震动大而且对架枪的方式很敏感。另外这个是给小朋友的考虑到安全扳机估计会很重，我觉的你水平偏差巨大恐怕是用力猛扣扳机的结果。

如果有$400的预算可以上个入门PCP。$500来个Benjamin Marauder这类主流PCP。全系统包括枪/镜/打气筒。

如果弹簧的那就来气弹簧，金属弹簧的就免了。好一点的是Underlever的，不过选择少而且都不便宜，$200以上。折管的话就多了，Benjamin家的deal时$100多点就能搞个不错的，通常会带个4x32这种低档镜子。

感谢师兄耐心指点。回头我找gun smith先校准一下。后面考虑换家伙。

这个只能粗略归零，还是必须实弹打来归零，尤其是竖向上。

谢谢师兄。毕竟外弹道在垂直方向是抛物线。
