My issue was a round nose 9mm bullet.
You can NOT use round nose 9mm bullets unless they are 147 grain ones, the 115 and 124 grain round nose are too short and do not have a long enough shank on the bullet to be held in correctly for the 357 Sig, sorry but that is just a fact of life. (flat point maybe)
Purchase bullets designed for the 357 Sig not just ordinary 9 mm's.
