Does the Bullet's Tip Melt While Going Through the Air?

Have been told that bullets (with exposed lead tips) will melt from the heat / high-speed friction while going through the air.

Is this true? If so, then the uneven or jagged exposed lead tips don't matter too much because they will melt during flight.

And you have to ask if that is true. I hope the fella that said that doesnt hunt anywhere near me.

Okay let me guess here, you are about 16 or 17 years old and either someone is pulling your leg or you have very stupid friend. Big smile

if a projectile reached a high enough speed and was tipped with lead it is very probable that the lead would reach a temperature capable of melting it,wether or not a bullet fired from a standard hunting rifle could reach that speed is very unprobable.

I suspect the bullet would not be structurally stable under the forces necessary to achieve a speed where the tip would reach the melting point of lead. Just a guess....

It's not true, that the tips melt.

If they did melt, you would still need to pay attention to uneven or jagged tips.

The uneven tips would not instantly melt, thereby creating (for a time) a difference in the flight characteristics of the projectile. This would increase dispersion and reduce accuracy.

Lets see here. What is the melting point of lead? 621.5* F. So at what speed would the friction of flying throught the air reach that heat? Well we have to know the drag coefficient of the bullet. the barometric pressure of the air. Rate of acceleration. etc. etc. Needless to say it would involve some physics and calculus that I'm not interested in figuring out. Needless to say the speed required would be quite out of the realm of possibilities of modern guns.

Bahh... just set the velocity at zero and the air temp at 621.5F. ;-)

Tee Hee Bitmasher!

Another element would be time. Even if the velocity was sufficient to generate the needed friction, there would be an element of time necessary for the mass of lead to reach the melting point.

Most projectiles shot at 1000 yard competitions take a little over one second to reach the target. The time of flight over most reasonable hunting ranges is a few tenths of a second. Very little time for friction to heat up a dense mass such as lead.
