I've shot Perfecta in 38spl($14) and 357mag($16) out a 2.5" PC 686 at 7 and 10 yards.No misfires and decent grouping.The 357 was not under powered at all.
The Perfecta 9mm($9)all fired without issue and decent grouping out of a Sig P938.
The Perfecta 45ACP had really good groups out of a Ruger Redhawk 45LC/45ACP revolver using moon clips and a Smith 745 auto indoors up to 50 feet.

I've shot probably a 1000+ Perfecta in several calibers without a missfire or ftf/fte in the autos

The brass is good for reloading.
