枪不同,使用的子弹也不同。随着枪支的发展,子弹也在不断发展。手枪的枪膛很短,这要求它的子弹的发射药的燃烧速度很快———如果等到子弹出膛还没有燃完,发射药的能量就被浪费了。实际上有些手枪弹干脆就没有发射药,只有比较大的底火。常见的BB、CB弹,就是指这种枪弹。步枪机 Different guns use different bullets. With the development of firearms, bullets have also continued to develop. The pistol’s shot is very short, which requires that its bullet’s propellant burn quickly - if the sub-pop-up hasn’t been burned, the propellant’s energy is wasted. In fact, some pistols simply do not have any propellant, and only relatively large primers. The common BB and CB bombs are the bullets. Rifle Machine
