I was doing a little reading and stumbled across this:
For instance, low pressure sometimes pushes the cup backward part way out
of the pocket, then the pressure builds and pushes the case backward
over the top of the primer, fully seating it again. But in the mean time,
the cup tries to form itself around the firing pin and into the firing pin hole.
This isn't due to excessive pressure, just the manner in which low pressure
was applied.
My primers are more "cratered" than flattened. I measured the case webs from my HS-6 loads, and standard factory ball. My Red Dot loads do not exhibit any case bulging or excessive expansion. As a matter of fact, they measure exactly the same as all my brass.
Because I am seating my bullets to 1.250" as opposed to 1.190" as per manual, is it possible, I am running the pressure too low with these Remington primers?
