 | | Second, it excludes the traditional full power military rifle/MG cartridges such as the.303, the.30-06, the 7.92x57 and the 7.62x51 NATO (typically firing 10-12g bullets at 750-850 m/s, and developing around 3,000-4,000 joules), as these are so powerful that their recoil is uncontrollable in fully-automatic fire from the shoulder. |
 | | The downside is that the stopping power becomes more controversial (relying on velocity rather than calibre and bullet mass; which according to combat reports sometimes works, sometimes doesnt) and the long-range performance begins to decrease again as small-calibre bullets generally have poorer sectional density ratios, and thereby ballistic coefficients, than large-calibre ones. |
 | | A salvo-squeezebore (firing several stacked conical projectiles which were squeezed down to a smaller calibre by a muzzle attachment) was developed for the.50 BMG, but versions which have appeared in 7.62mm NATO appeared to have been made for their novelty value. |
