Title: high temp plastic jackets
Post by: kunkmiester on March 17, 2009, 02:17:21 am
I was thinking about this mostly due to a caseless idea I had, but I don't see why a plastic case is hard.  They had the teflon bullets, before they were banned.  I'd imagine that swaging plastic over lead would be easier than copper, making jacketed ammo that can do higher velocities and such easier.

Teflon is an obvious one.  Any other plastics?  What kind of issues would you have to deal with?  Any legal issues, aside from the teflon?

Teflon isn't illegal for anything like that.

18 USC 921(a)(17):
Quote
  (B) The term `armor piercing ammunition' means-

  (i) a projectile or projectile core which may be used in a handgun and
which is constructed entirely (excluding the presence of traces of other
substances) from one or a combination of tungsten alloys, steel, iron, brass,
bronze, beryllium copper, or depleted uranium; or

  (ii) a full jacketed projectile larger than .22 caliber designed and
intended for use in a handgun and whose jacket has a weight of more than 25
percent of the total weight of the projectile.

  (C) The term `armor piercing ammunition' does not include shotgun shot
required by Federal or State environmental or game regulations for hunting
purposes, a frangible projectile designed for target shooting, a projectile
which the Secretary finds is primarily intended to be used for sporting
purposes, or any other projectile or projectile core which the Secretary
finds is intended to be used for industrial purposes, including a charge
used in an oil and gas well perforating device.

Federal Nyclad bullets have been around for quite a while as have Remington Accelerators and other sabot rounds that hold a sub-caliber bullet in a plastic cup.
