Ive bought some of this ammo for my Enfield #4
It is pretty decent.
Pakistani manufacture (mine was 1965)
Berdan primed, brass case (marked POF 65 7)
Corrosive primers (make sure and clean your barrel after each session)
Clean (no corrosion) reliable ammo at a good value.
Considering it was made 40 years ago in a developing nation accuracy was pretty good
