请问栓动靶枪多久该擦一次。。。？

FJC

SSG3000已经打了好几百发了，还没擦过，“精度”好像也没下降，今天打的靶纸除了一组自己发挥很失败的，其它的组好像比以前成绩还提高了点，请问是不是该擦擦了，还是该等到精度下降再擦？（听说太频繁擦枪会破坏精度。。。但是总不擦是不是也不好？）

很多枪都是脏了准，千万别擦太勤快

今天看上去还真很赞！什么配方？？？

还是跟以前一样的配方，168smk, 43.4gr4064
现在打算配方不变，多在顶枪控枪上练练了。。。这个load要换了你打，0.5moa all day long估计问题不大

要不就还硬扛着不擦，等过一阵野战完了再狠擦一次。。。

很多人一周用bore snake过一遍

nothing good can come out of a clean bore.
i suggest only clean chamber and bolt face every 100-200 rounds, only clean bore when your 1/2 MOA groups all go >1 MOA.

Very stable loads.  

I stopped trying different seating depths now, since I got 5 groups of <1/2 MOA with 43gr 4064 & 175 SMK, 0.020'' off lands.  

The only thing I plan to try next is the Berger 185gr Match bullets because of its high BC and my 1:10 twist.

Went to 1000 yard range yesterday, and failed to hit 1000 steel with 168gr handloads. All the 175gr i brought was used on 800 and 900 steel.  When it came the time for 1000 yards, I had only 168gr left

My 168gr handloads can only reliably hit 900 yard steel, but no further.  14mph wind is causing all havoc on them.

Heading out today again with my newly loaded 50 rounds of 175gr.  Hope to get 1000 yards today.
My next rifle must be a 6.5 creedmoor.  308 is horrible dealing with wind.

Try 155gr Lapua Scenar. 168gr only good for 800y.

看来half moa是一点压力也木有

我怎么觉得压力很大，从来没有5x5平均到过half moa，赫赫

那帮玩6mm PPC的好象是打一发擦一次

我也是看到打Benchrest的经常擦，特别是北欧的高手（世界冠军级）几乎每发都擦。每次都用大量像油一样的东西清洗一遍（不是反复擦！），然后用干布过一遍。过程很简单。我想搞清楚那像油的，到底是什么东西。
我比较懒，几十发擦一次。好像也可以。
