Primer Differences?

[Toolbox X]

I'm a n00b. What is the difference between:

Small pistol primers and small rifle primers?

Small pistol primers and small magnum pistol primers?

5.56 military primers and small rifle primers?

Size. Rifle primers are taller, rifle brass has deeper pockets.

Small pistol primers and small magnum pistol primers?

Magnum primers burn hotter/longer to burn more powder that is expected in magnum loads.

5.56 military primers and small rifle primers?

Military primers will have a harder shell to avoid accidental discharge/slam fires by floating firing pins.

Excellent and swift answers. Helpful for me as well. Thank you!

Grant, I hope all is well and that the loading saves you lots of money! I still love my stock!

Rifle primers are made thicker to run at higher pressures than pistol primers.

Military primers for machineguns are made harder to make slam-fires less likely.
