Strange old ammo [View all]
While sorting thru a shelf of ammo I came upon a box I don't remember having.
Caliber: 223/5.56mm
Bullet: 62gr FMJBT
Made by PCA- Spectrum/Natec
It has a part polymer, part brass case. The base and about 1/4 of the case is brass, the rest a white polymer. It's a full box of 50 rds.
Any ideas? Has anybody heard of this? The closest I have heard was some experiments with a full polymer case. There was a consistent failure to extract, the extractor pulling thru the case at the extractor groove.
