Prometheus air gun pellets

[BFG Central]

I remember Prometheus pellets from way back when i was about 16. (25 years ago) and at the time you could buy them ready made or put the two parts together yourself and save a bit of money.
The best (Most destructive) pellet i ever shot were called Nato Bullets and were an alloy pellet.
They would go straight through an old galvanized steel dust bin and lodge in the other side. Then we used to knock them out with a hammer and use them again over and over again.
I still have a few in a tin some where.

Back on topic, Prometheus are ok but the plastic will clog your rifling up over time.
I do have some in the cupboard but i always reach for the bisley mags when i go shooting.
