Chris,

Can I ask why you are using a .358 mold for 9mm? I've slugged the barrel on my SP-01 and got a .3555 measurement. Going to that large a slug is going to require a shorter OAL as the ogive of the bullet will contact the rifling that much sooner than a smaller diameter bullet. CZ's are known for short leades and requiring a shorter OAL to begin with. Going with an over-sized bullet is just going make matters worse. Have you slugged your barrel? Unless you got a measurement of .357, there is no need to go .358 on the mold.
