My son is buying a set of dies so I can reload for his SKS. I would like to use the Lee Soupcans that I shoot through my bolt and lever actions to save a little money. I've heard that cast in a semi will clog the gasport but I have no personal experience in reloading cast for semis. So I seek the knowledge of this distinguished forum on the care and feeding of a Chicom assault rifle. Thanks in advance for your advice.
