Perforations are somewhat context-dependent. I get about 4-5 perfs/25 shells when I use Rios in 16 ga RGLs. I have several 16 ga M-12s and they all do this. I haven't had a Rio perf in AAs or STSs fired in my 12 ga 391.......guess where the rest of my Rios are going to be used.
Cheddites don't seem to perf as often as that. Fiocchis are better, get me maybe 1 perf/sleeve. I have yet to have a Wolf 209 perf (4000 so far), and they are dimensionally closer to domestic primers than the others. The Wolf primer cap is almost as hard as those Rem GL and GC factory primers.
