I was recently given a complete box of ammunition by an aquaintence who kenw I had a lee-enfield. The ammunition is in a FN sealed cardboard box. The seal reads

POUDRE BUSKRUIT
CART.Cal. - PATR. KAL.
303 C.T.N
POUR F.M. BREN
VEOR M.G. BREN
______________
F.N. LOT 10 f/51
Cde - Best.
S.A.A. N'Ag. 34/1/18

The individual rounds are headstamped
F N
51

The box is in excelent shape, with all of its rounds also in good shape. I wanted to make sure this ammunition wasent worth anything to a collecter before I go blast it.

If it were me I would keep the packet and one round for collection , then go shoot the rest of the ammo off.

Its Belgian ammo rated for use in a brengun , so it will be fine for rifle use , and the more you shoot off the more the remaining stuff goes up in value .....
