PolyCase Ammunition are an injection moulding company in USA that has developed a range of nylon/copper filled polymer bullets . The raw plastic has copper particles blended in that provide some mass to the self lubricating projectiles - then the melted material is squirted under pressure into the mould cavities.
They say that they are currently producing their bullets at a rate of 90,000 per eight hour shift from two 80 ton presses and they come in eight different sizes that can be loaded into conventional brass cases.

Injection Moulding is a way of bulk producing plastic components cheaply. The moulds or 'dies' are expensive precision engineered tools that are fitted into big heavy powerful machines that can run continuously with little attention when set-up right. - I should know - as I worked in the UK plastics industry for decades as a machine setter / supervisor!

It costs a lot to set-up - but once running the unit cost is negligible (- peanuts cost much more!)
So this range of light-weight ammo should eventually be on sale as a low cost choice - once the initial investment cost has been amortised - it's all profit.

- Yeah, that's the kind of stuff I used to do before NZ
As the name 'PolyCase' suggests - they also produce plastic cased ammunition.
I'm not able to say if this stuff is any good - but I don't doubt that it will be fine once all the wrinkles are sorted.
- Well, - plastic bullets in plastic cases to fire from plastic guns - what will they think of next?!
