If a bullet exits a barrel at 3000fps. Does the breaking of the sound barrier by the bullet influence the BOOM that you hear.
But only some - it greatly increases errors due to things like wind and geometry (distance, height, etc). Firing a sniper rifle isn't actually all that much different than firing an artillery shell.Originally posted by Njorl
Actually, there are some silenced sniper rifles, but they use subsonic rounds. They are very interesting. They make up for some of the lost accuracy by imparting much more spin to the round.

Does anyone know of some more general information on speeds, wind effects, etc, that go into sniping? It has always interested me (in a physics sort of way, of course).
Doesn't make a lot of sense that a subsonic would fire further than a supersonic round.Originally posted by FUNKER
i read this thread and happy because i have always wondered why they havent been silenced in movies and wat not, so anyway in my hype i told a friend of mine who was a gun collector. He told me that the record held for the greatest distance a sniper rifle can fire was 2.6 km, this was held by a subsonic rifle. hmm? Any one wanna comment?
Body armor is designed for specific impact energies, so it depends on the gun/bullet. A .50 cal high velocity bullet at 1/2 mile would barely even notice a kevlar vest and would go through your body like it wasn't even there.Originally posted by Link
Do you think body armours would do the work protecting u if someone snipes you from lets say, 1/2 miles distance? They are designed for it right?

If I hear about anybody in body armor getting sniped with a subsonic rifle, I'm gonna forward this to the FBI.

This kevlar armour is getting intresting.... can someone explain how the material can protect you from a supersonic bullet with just a few inches of thickness? According to newtons third law, no matter how strong the armour is,the force cant be eliminated, right?
