If the cup surface is struck from the firing pin, the middle collapses, squeezing the explosive compound among the interior of the cup as well as anvil. That ignites the compound and sends a flame through the case flash gap, which in turn lights up the propellant.
thirty-06 exam masses show flattening—in just nutritious boundaries— and when it’s a small sample sizing determined by just one propellant style, a single bullet style, in a single caliber/scenario mixture, I gleaned some attention-grabbing observations.
Berdan primers depend upon an anvil that’s built in the primer cup spot from the cartridge case itself. For deficiency of a much better term, you’ll see a little bit “nub” that protrudes into the primer pocket region of the case.
I did observe that Federal’s primers—both equally grades—manufactured drastically smaller velocity Excessive distribute and conventional deviation. This proved accurate Using the 6mm Creedmoor in addition. You may see the whole details over the accompanying chart.

I have never had a dilemma. I often fall primers on the ground, at times they wander off in every one of the fired primers on the floor And that i vacuum them up jointly and eliminate them from the trash. Never had a primer explode on me except when firing them in a gun. Probably I have just been lucky for fifty decades.
