Came across some dies in these calibers. Does anyone know anything about them? - dan

might be off here.
if i recall right.
they were waay ahead of thier time and are similar case volumns to the wsm's around now days.
but at a lower pressure level [52k?ish]
i am not sure of the parent case but 348 win comes to mind, and they might have trimmed the rims and cut extractor grooves.

Thanks Lamar. I was debating picking them up, but couldn't find any info. - dan
