SRP vs SPP

9mm, Looks like you shot them in a Taurus GX4.
I loaded some SRP in my GX4 and got the same
results. I've shot SRP in several pistols without a
problem.

Allegedly, some military priming compositions are formulated to have lower impact sensitivity to minimize the possibility of slam-fires in automatic weapons.

The #41 style mil-spec primers not only have a tougher cup but also greater distance between the cup and anvil. As far as I know, the primer composition itself is the same as a standard SRM.
Anyone with an AR can perform a simple experiment to see why. Load two cartridges in a magazine. Fire the first one, eject the second one. Most rifles will leave a dent in the unfired primer from the floating firing pin.

It leaves the same primer imprint the Taurus GX4 does.

Rifle primers have thicker cups than pistol primers.
As long as you do not get any light strikes and misfires you should be okay.
The rifle primers are thicker to contain the higher pressures generated by most rifle cartridges.
I have read recently some brands of rifle primers are a tiny bit larger in diameter, which might be an extra tight fit in some pistol brass.

Yesterday found Academy Sports had SRP for $6.99/100. Bought 15 boxes and called good friend. He came over as he and his wife were next door in Aldi's. He bought 10 and still plenty left. My question is IF and When they get SPPs in will they be $6.99/100???
Taking bets that they will be Higher…
