Because the centre of gravity is near the rear of the projectile, the Russian bullet starts tumbling, as it leaves the barrel.
Ok, where do I start.
Firstly, a hollow point is not the same as an air space in the tip (although it is still technically correct to call it a hollow point), that's what
the Russians did with the 5.45, and they weren't the only ones. These bullets don't tumble as they leave the barrel (sorry have to have a little
you wouldn't hit a barn door at 10 yards with a non-stabilized bullet. What they were designed to do was tumble when they hit something soft
and squishy, something that all bullets do, it's just that some don't do it quickly enough, and that's what the Russians were trying to fix.
Traditional hollow points or JHPs are designed to "mushroom" when fluid under pressure enters the open tip, thus increasing the wound area and
slowing the bullet inside the body - generally referred to as energy dump. Dum Dums (named after the British arsenal in India that first designed
them) are NOT hollow points, they are standard FMJs that were formed with the tip of the copper jacket missing, thereby exposing the lead core, today
we call these soft points. They work very well in rifles but are largely a waste of time in pistol ammunition where the velocities are inadequate to
cause much expansion.
Next - no, the 5.56mm was not designed to wound, that is a total armchair commando myth. It was designed to kill, and the primary mechanism for that
is bullet fragmentation typically at the cannelure where the jacket has been weakened. The 5.56 lives and dies by its velocity, and if you are
shooting the mil std. M855 round out of a 14.5 inch M4 barrel at someone 300 yards away, all the wounds will be "ice pick" in nature - no
fragmentation, limited damage.
Finally, yes I have shot both 7.62x51mm and 5.56mm, but not at people, and 5.56mm is a great round, but not ideal. It is a great round for civilians
who can use soft tip or JHP ammunition, but has restrictions for the military who can only use FMJ and may need to engage at longer range. For me,
and this is a highly personal opinion, 7.62x51mm just has too much thump - we Americans have been idiots in pressing other nations to adopt our ammo
preferences, when all along the British had it nailed with their .280 round in the late 1940s.
So what we have today is the Remington 6.8SPC, arguably the best of both worlds, and a great round IMO, but what ballistics does it replicate? why
.280 British of course. Sorry Britain, our bad.
But me, well I guess I'm a little old school, because I still have a strong liking for the simplicity and effectiveness of plain old Russian
7.62x39mm, and that's what I use.
