What is the speed in the air and compare to speed with the military planes and bullet?
Answers
Usually a rifle bullet is significantly faster, i.e supersonic, than any passenger aircraft.
However, subsonic .22LR is a fairly common rifle round used for varmit and pest hunting. it’s quiet (no supersonic crack) and it doesn’t travel so far. So in some cases it will be slower than a passenger jet. (A 747 can if necessary legally travel at M0.88, - I was on the flightdeck of one that was doing so back in the late 90s. Long story….)
Pistol rounds are sometimes subsonic, especially ammunition purely for target shooting, e.g. a .38 wadcutter might be doing 500 mph, slower than many passenger jets. .45 acp is also subsonic, about 600 mph)
But regular rifle rounds are far faster than passenger jets, e.g. a 5.56mm is doing about 2,000 mph, much quicker than Concorde ever flew.
