So....the speed of sound is aprox. 600 m/s and a rifle(for ex. a Mauser K98 Karbine) shoots the bullet at aprox. 1500 m/s (sic!)(that's pretty damn fast
) so it is supersonic! For ex. if you are standing at 1000 m in plain ground and someone shoots at you whith a K98 sniper rifle you will be hit by the bullet and then hear the sound blast of the gun( so you're dead before you hear anything )- well that's quite silent for me . Another thing, i think i have read something about this in my youth and i know that at great speeds(more than the speed of sound) projectiles tend to be a little unstable(like missing targets and so on...). That's why the barrel of the rifle has a specific design that gives the bullet a rotation movement that stabilizes him(isn't that right?). So thats your answer!Someone has wrote that whaen the bullet breaks the sound barrier there will be a "bang". Well, i don't think is wright! The bullet has a small volume and a small mass so whebn it's supersonic you'll hear only a slight "wheeezing" when it passes by you.IT is not a supersonic plane (that's a "bang"!).The sound of a shoot isn't done by the bullet himself, but by the gases that expand quickly liberating energy against the air molecules to create a sound! So the silencer is maked to absorb that energy so the sound will be weaker ( that doesn't mean that the bullet isn't supersonic!) This is just like shooting thru a pillow pressed to the barrel(more quieter!).
If i wrote some rubbish in this topic please corect me!
I am very interessted in the tema!
