Ready for a dumb question?

Do you have data to back this up? My only report on this subject is a couple of decades old and not current.

This needs to be proven with Brinell hardness testing and measurement of cup thicknesses.

Rifles operate at higher pressures and have more robust ignition systems. Pistol primer cups are thinner and probably the anvil gap is less.

Just try some rifle primers in a pistol and experience the misfires. You will figure it out.
