Attached is a photo showing a Speer .357 Sig 125 grain Gold Dot and a generic 9mm 124 grain round nose alongside a Sig case. Also included is a 9mm 124 grain Hornady XTP-HP and 125 grain HAP alongside a loaded round with the XTP. The truncated cone shapes of the Hornady and Speer bullets incorporate a long full length bearing surface that provides proper neck tension.
None of the major reloading manuals recommend using standard 9mm round nose bullets with the Sig case due to their shape and possible lack of proper neck tension.
