.303 cartridge MK7z PP-73

[David TS]

Hello all.
Im a new member located in Queensland Australia, I must say feeling a little lost, as this is all new to me, as I have never signed up to any on line forums in the past.
I am looking for good advice on .303 cartridge MK7z Prvi Partizn ammo I have a chance to purchase. They are in box's of 15 marked PPU7301 MBL7111 POWDER NITRO-CELLULOSE. Headstamped 303 MK7z PP-73, with red sealed primer.
This ammo is very clean from a freshly opened wooden ammo box, looks as new.
I know it is Yugoslavian, but I would like some feedback on anyone who is familiar with this ammo.
Is it corrosive ?, reliable ?.
Your help would be much appreciated, as I would like to shoot Military/full bore with this ammo.
Cheers Graham.

For the purposes of political sensitivity and correctness, the PPU factory these days is in Serbia not Yugoslavia

PS, I use it regularly in my No 4 (T) and L1A1 SLR, good ammo
