I am looking for load data for the 8 IHMSA. One book I have says it used 308 brass necked up and trimmed. Another source says it is a 300 Savage necked up with a 38* shoulder.
I would like to know the parent case, load data with heavy (200gr +) bullets and where to find dies.
If anybody has a used set of dies that they want to part with - that would be great!!
