I'm a C&R holder and get about a half dozen flyers from different sellers and while on the pot last night I came across some 9mm that uses a plastic bullet and is around 30 grains. I forget who was selling it, possibly Inter Ordinance, Century or Centerfire. Said it was a safe practice round and they only cost about 5 bucks for 80. I'm tempted to get some to try out but wonder if the plastic could get stuck in the rifleing of the barrel? I'm assuming it's a pretty hard plastic, but it sounds like this could be a fun round to use for practice in the backyard or something provided it's accurate.

i've seen plastic german rounds. they're accurate out to typical combat pistol ranges and they ARE made of hard plastic. i've got a box of 9's and several boxes of simunitions (course, they're not made to fire out of real firearms).

ETA: also have some east german plastic ak practice rounds.

This confuses me. Perhaps some of the ballistics backyard physica people can help me understand.

I would think plastic though a barrel would end up melting, or at least leaving resident at a certain point. Of course, I'd imagine the friction of plastic on steel would be less than lead on steel.

How would plastic maintain the rotational velocity without the mass of lead?

No gunpowder. Powered by the primer only.

Nope.

The Hirtenberger 9mm Plastic ammo with a 3Gn (not 30Gn) plastic bullet has both a primer and powder charge. They sell for $2.97 a box at SG

30Gns is as heavy as a CCI Stinger bullet or some 25ACP loads. The Hirtenberger plastic 9mm ammo weighs 3Gns.

The only use i could see for it is a 9mm revolver as it wont cycle the action of a semi.

Ahhh, gotcha. The 30 grains should've been my clue.

Has anyone shot these out of a semi-auto? I'm gonna pick up a box just for fun, but wonder if there's enough propellent to make them cycle? They say they are training rounds so I imagine they would. Also how loud should I expect these to be? I'll be shooting in a suburban neighborhood on an acre lot, with no neighbors for 1/4 mile behind my backstop.
