He, he he,

I use the punch and hammer method for straight walled cases.

I just make up a tip to a punch with the diameter of one of the flash holes and insert the punch into the flash hole and tap out the primer, not a real fast effort, but it works.

I even use it for my berdan primed 577 Snider cases.
