for what it is worth
I have used the CCI 41s in my carbine with no issues
I have also used CCI SR primers
Currently I am useing the WOLF brand primers that are advertised for the 5.56 which they describe as a SR magnum primer with a slightly harder cup
All work well, all crony around 1900fps with my largest deviation being 12fps
14.5 grains of 296
