A shipment of 125 grain JHP from Montana Gold is on it's way and is overdue to be delivered by the USPS. A set of the Lee 357 Sig dies are going to be used for loading my first batch of that caliber, so I will let you know if the same issue happens with the cases getting scratched using those dies. I have a mix of once fired and brand new cases to choose from for testing, so any scratching should be easily noticeable when using the new brass.
