That is not exactly true, as John Linebaugh's pressure tests proved in the Linbaugh revolver cartridges pressure increased with large rifle primers without a corresponding increase in velocity
The theory was that the rifle primer was over lighting to powder effectively increasing the burn rate
How this relates to 9mm and small rifle primers i have no idea




I got banned on another web site for a debate that happened on this site. That's a first
