Have you contacted them? Unfortunate for you. I have prob 6k pieces of alpha brass between several chamberings, not any of them are excessively tight to your description. If there's a problem, they'll ikely fix it.Just to be clear, the batch of Alpha brass I received is not normal. The pockets are simply too narrow to prime correctly. This brass is out of spec and is garbage.
Any benefit from Alpha having a tight primer pocket went out the window the minute they starting shipping garbage product.
