Exactly what should be expected. Remember powder burns it doesn't explode. Need to contain it to build pressure and get a full burn.

The video will not play for me but I can pretty much guess what happened and why. The primer was set off by the bullet impact, the powder was ignited until pressures climbed enough to rupture the case which then dumped the unburned and incompletely burned powder onto the ground. The powder was not consumed as pressures never reached a high enough point to burn properly.
This is similar to what happens with most civilian/commercial ammunition too. The differences are civilian ammo does not have as robust crimps of the bullet and primer which tends to cause the pressure to escape out one of the ends rather than the sides. Not to say cases never rupture but it is not as common.
When gas escapes by pushing out the bullet, the bullet tends to go a couple inches at most. Velocity never reaches a point in which it becomes dangerous. The primer being pushed out is common and it can travel a couple feet in best/worst case. The primer is light enough that it poses lttle risk of injury due to rapid loss of velocity. If close and unlucky enough one might suffer an eye injury due to the primer but little else.
