I am happy to see your post about SIB. First let me correct the exact address whixh was “rue des Moines” (i.e. Monks street), and not “Oines”, which strictly means nothing at all !
I knew quite well Stefan BULKOVCIC, a Serbian guy and a a former military shooter in the Yugoslavian shooting team at the first Olympic Games held in Korea…
We met at the Military Firing Stand, Satory, when I was shooting my Tokarev TT33 and the regulation MAC50 within Naval Reserves, back from Polynesia in 1986.
He became one of my patients when I settled a civilian practice this very year. I took care of him, and also his daughter and wife then, and… happily he took it very well (as an oral and maxillofacial surgeon, I removed all their wisdom teeth !!! excuse me for the Medical Secrecy…).
In France where he came as an immigrant in the 60ies, he married and founded a family. As he was still very much interested by weapons and shooting, he created a small family society, where he began to reload and make ammo for the Police, thanks to his connections. He was working only with his wife and son-in-law, in the basement of his house…(his wife was almost intoxicated by lead fumes there, till I told him to stop quickly making her mold projectiles in a badly ventilated local…! the story ended in hospitalk , for the poor woman , but happily, everything went OK and I got a crate of Champagne for that!))
At the time appeared the so-called ARCANE and THV super-penetrating rounds, and he decided to devise his own bullets designs, to be concurrential…but the law did change and this ammo was outlawed (same as the KTW in the US).
Anyway, he had the idea to load pistol ammunition on the line of the old .45ACP WW II Survival rounds, i.e. with diverse kinds of lead pellets…
The pellets were contained in plastic caps obtained from SPEER . As his step-brother was an engineer in the French subsidiary of the Dutch Phillips S.A., making plastic materials, it was relatively easy for him to obtain the making of such caps for his own use, which were firstly made in polyethylene, but later on in styrene, for better desintegrating ability out of the barrel.
As far as I remember, he began to load this ammunition in the beginning of the 90ies, and made them until 1995, when he decided to close the shop and move in So.Western France to start an agricultural business, plantig trees… (one of his old dreams!).
About the massive hemispherical copper bullets pictured here, they represent another trial, which also failed after the so-called Arcane Failure. Originally designed at the defunct SFM, he modified them and got them made especially in relatively small quantities.
I must say that Stefan was not very regardant about patents… and often infrnged them…being lucky to have no problems afterwards.
So my little story ends up now. I hope to have been able to herlp your curiosity!
All the best
