Primer flow as in... pierced primer? Do you have any pictures?
Factory or reloads? Have you had a look at the firing pin in the pistol to make sure it doesn't have a burr or isn't jagged and partially broken at the tip?

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.
