First off let me say I don’t advise or suggest anyone else try this, it was my own experiment.
We all know primers are gone, and SPP are getting burned up the fastest. Fortunately I have some leftover S&B SRP and did some caliper measurements. Surprisingly everything is identical to my CCI SPP including cup thickness, so I loaded up a few and knowing the rifle primers are ‘hotter’, downloaded the charge a bit.
Primers all seated flush or slightly below in 9mm and 45 with small primer pockets. Guns used are CZ 97b custom, P01 with lighter hammer spring, stock P365 and new Citadel 1911.
The P01 didn’t have enough ‘oomph’ to hit the primer hard enough, so multiple light strikes. Same with the 97b, the 365 surprisingly lit most but one in ten didn’t make it. I guess least surprising is the 1911, zero FTF.
As I said, just an experiment with the shortage happening. The S&B SRP cup is not thicker, but made of a harder material and obviously has more energy for lighting difficult rifle powders.
