Kinda sounds like you have a DUTY to write to Speer!
Your best bet is Ben Amonette @ ATK. He's the guy who is first to respond to technical inquiries through the Alliant data source site.
Of course, he's an ATK guy. Maybe you'd rather find a Speer-specific guy. He might be the guy to get you the contact details you need.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
