所以點解呢次美佬打伊拉克D M14 出返晒
因為於沙漠的開闊地型, 5.56 最多400m嘅射程唔夠洗
well, actually, it's not that the bullet velocity drops too much, true it drops a lot after abou 350m, BUT given a good shooting condition i can hit up to 800m with my Bushmaster Varminter.
the problem isn't the drop it's the wind. once it gets windy, 5.56 doesn't work good at all. my Bushmaster usually pushes .5-.7inch groupings at 100m, last time, when we had 50mph winds here i was shooting 4.5 inch groupings... it's an extreme condition, but at the same time, the effect of the wind on the bullet could clearly be seen
in my experience, the 7.62 bullet resists wind a lot better. it's not fully resistant to it, but it still is pretty good against it, compared to 5.56
