An old range buddy of mine since late sixties in the meanwhile became a gun authority and a well known gun magazines article writer. This time he had to test a new .357 Fiocchi ammo, the Top Defence line Black Mamba (I wonder why they use always only silly names for sale appeal). After a couple of sessions he realized cylinder start to disappear as it would have been melted and gauged by burning scandium particles. Pics show it better than words. In the first, the ammo box, the muzzle blast and that nice firework like burning scandium (I suppose).
Obviously he wrote S&W to explain the trouble and they told him " Too lightweight bullet".
Is there anybody can add more?
