The Portuguese ammo was covered on a previous thread here not long ago, entitled "8 x 56R Kropatschek “F.A” Manufacture, which turned into an excellent thread on Portuguese SA Ammo manufacturing. The “BF” headstamp appeared mostly in Southern Africa, with a lot of it coming out of RSA. It was made for there, but I am not sure which country specifically. No one, even the Portuguese, know exactly what the B.F. stands for, only that the purchaser requested that headstamp. Our friend and Forum contributor Vitor Teixeira recounted that when FNM largely shut down its ammo activity, most of the records and archives were destroyed, so it is probable that we will never know the answer of “B.F.” and “A.S.C.” etc., unless someone in South Africa or Southern Africa is forthcoming with the information. It is doubtful that many there would know, either.
