哇塞，大神来捧场了。
去年拿到枪证的时候搜索论坛精华枪贴，拜读过不少您的帖子。
我们俱乐部可以射200 ...
大神二字实在不敢当，高手多着呢，只能说是同好。
如果你买不到surplus的话可以参考一下网上的资料，不过得自己深究一下。每一把枪都不一样，而且压子弹有风险，所以没有人敢教你具体用什么数据，只能说我自己是用某某某数据的。
Military 6.5x55 ammunition was loaded to a pressure of 3200 ATM which converts to 47008psi. Proof loads developed between 4000 and 4500 ATM which converted (x14.69) give pressures of between 58,760psi and 66,000psi. The original m/94 military load featured a 10.1 gram (156 grain) round nosed bullet which achieved 725m/s (2378fps) in the 29" barreled m/96 rifle, 700m/s (2297fps) in the 24" m/38 rifle and 655m/s (2149fps) in the original 18.5" m/94 carbine. The first pointed bullets were tested between 1910 and 1920 in experimental rifles, the final load appeared in the M/41 sniper rifle and used a 9 gram (139 grain) pointed bullet. This load quickly proved itself superior to the former and in 1944, the 9 gram load replaced all of the previous M94 designated ammunition. The M/41 load achieved 793 m/s (2601fps) in the 29" M/96 barrel, 768 m/s (2519fps) in the 24" m/38 barrel and 730 m/s (2395fps) in the18.5" M/94. Many Swedish rifles still bare a brass disc on the butt which helps tell the user which ammunition the rifle was sighted in for, its zero - and the condition of the bore since its last inspection.
买最接近的弹头，根据muzzle velocity推出你用的火药的火药量，再根据自己的枪的实际情况测出最佳OAL，估计跟军用弹也就很接近了。再说军用弹的精度肯定比不上你自己一颗一颗地称火药跟手工压弹，也随时秒杀现代商业弹。个人的射击技术固然重要，但是确认枪况跟最佳子弹数据还是要先解决的，人才是最后的因素。否则打了几个月耗了几百发子弹，最后才发现不是人的问题，是枪跟子弹有毛病，那就花冤枉钱走冤枉路了。
自己压子弹不是为了省钱，是为了提高精度。有钱买枪但是没钱买好子弹的人是少数，明知子弹不合适还硬着用，还不如不打。 |

更要多试试才行，每种弹打一包估计都不够，好在6.5x55也是不是最贵那一类的，平均也就2刀一发
