Re: Type 95 assault rifle
Based on what I know and in regards to that video of the bullet:
1. That bullet seemed to lack any yaw and spin. The bullet went pretty straight past the armor and through to the back of the blob.
2. All that motion in the blob seemed to be shock, not the yaw and spin.
3. Medical studies show that human flesh does not get greatly injured by a bullet's shock. The human flesh is quite flexible.
4. The M14 and M16 is reported to poke a straight hole through unarmored people (i.e., Vietcong, terrorists and Iraqi independence fighters/insurgents/whatever), so an M14 or M16 needs one head shot or lots of body shots to QUICKLY put down a person. The M14 and M16 responds to different types of armor differently.
5. The AK-47 goes straight pass you, too, but it hits a person with MUCH greater force and it penetrates objects/walls MUCH better than the M14 and M16. Because of its iron sights, the AK-47 has worse accuracy than expected. With good iron sights, the AK-47 has good accuracy.
It's premature to say that the QBC95 is a bad design, whether the rifle or bullet. There is no such thing as the perfect gun or perfect bullet. A perfect gun/bullet is as rare as a perfect automobile (they all have their pros and cons): roadster vs. luxury sports sedan vs. high-mileage economy car vs. hatchback/station wagon vs. exotic car vs. truck vs SUV vs minivan. Which automobile is "the best?"
The compact bullpup rifles allow users to gracefully move around tight and crowded areas for stealth assaults or rapid assaults. In such RAPID, close-combat situations, it is rare to switch the rifle from your right shoulder to your left soldier. Most often, it is bad technique, because it ruins your aim and forces you to be overly cautious around corners. With proper stealth or teamwork, you do not need to switch your rifle from shoulder to shoulder as you go from corner to corner.
If the enemy is waiting for your team behind a corner, then the enemy is aware of your team's presence. In such fire fights, it is most often better to toss a grenade (don't worry about the "boom," because the enemy knows your team is here anyway), than to try to out-snipe the waiting enemy around the corner by switching your rifle between your shoulders depending on left/right corners.
Snipers in slow, long-range combat situations rarely switch the rifle between their right and left shoulders.
Conventional rifles should be easier to aim with as long as the environment is open (not tight and crowded). They also allow left-handers to use them on the left shoulder. They are better for bayonets, too.
In regards to bullpup rifles expelling dust and gas, a well-designed bullpup rifle should not have that problem.
