When you very rapidly compress air in the presence of anything that is remotely flammable,
If this is caused by the diesel effect, yhen why hasn't it been seen, over the years, before in other slo- mo vids? What is the particular "fuel mixture" cause with this bullet caliber / rifle, hel composition, weather condition that would cause that? Surely, one of the bullet / powder mfgrs could find out.
What changed? Laws of physics?Things have changed, there was a time when atmosphere was compressed moisture became visible. Some of the most interesting effects I have seen came off the end of propellers in what looked like a screw effect on humid days.

Amazing it ran at all with the intake manifold left off.In the mid 50s there were 500 cubic inch inline 6 cylinder engines that had a hemispherical piston design. It seemed it escaped the notice of most mechanics but the exhaust manifold was mounted on one side of the engine and the Intake manifold was installed on the other.
I understand none of this means nothing to reloaders but the mechanics rebuilt one of engines and then decided it did not need all of that plumbing so they left it off
Then came the time for the road test; they had to take the truck off the highway because it would quit running after a few miles. It bothered me to see that magnificent old truck confined to the yard for moving equipment locally.
