Some brands – except RWS – of common (outside America) 9.3x62 brass are even better for reforming to 9.5x57 M-Sch than scarce (outside USA) .35 Whelen. But watch out: RWS brass f.i. has thicker walls in the shoulder area and needs neck reaming or turnig after setting the shoulder back. Others, like S&B, Norma or PPU do not.
