Ok, I was reading through the Ballistics thread and someone mentioned Teflon
coating bullets to make them Armor Piercing.

Me and my friends had this discussion awhile back.... Would Teflon actually
work?
We don't think so. If you tried to use spray-on Teflon at home, the coating
would melt off due to the friction as the round spirals out the barrel,
warping the rifling and removing the Teflon coat. (Ruining the gun and
making the bullet less effective.)

Can someone prove me wrong? I also need the answer in case one of my
players tried this.

Why would the teflon coating warp the rifling of the barrel and ruin
the gun?

The reasoning was that the friction would heat up and melt the Teflon,
causing it to stick to the rifling once it cooled.
You could replace just the barrel, but how many players think of that?

No. It's a story started by some ammunition from KTW that used a bullet
machined from solid brass to improve penetration performance (the brass
didn't deform and so the bullet could penetrate better) - it had a PTFE
coating to protect the rifling of the barrel from the brass (much harder
than the usual gilding metal jacket).

The PTFE has no effect on penetration performance, just on reducing
barrel wear by the hard projectile. However, the media reacted with its
usual regard for accuracy and assumed that the Teflon coating magically
assisted armour-piercing performance.

is a good source.

Then, next time you fired a round through it, it would heat up the
teflon and no longer coat the lands so much... I don't think this would
interfere with the rifling at all...

Umm....semi same lines, why don't you just dikote the barrel? The round
will have reduced friction, thereby reducing recoil, increasing power,
and possibly even increasing the accuracy because of the reduced
recoil...

It just ocurred to me that the people who wrote CC might have been
referring to this when they said APDS (or AV, I don't remember which now)
ammo had a "bronze" core :).

Wouldn't that help following rounds?

Those who think about how not to be traced? Kill someone with a pistol,
collect your brass, replace the barrel, and there will be very few traces
linking the bullet to the weapon used.
