I just got a Ruger SRH .454 and want to do some reliability testing.
anyone know who makes the hardest-to-set-off SR primers?
I was thinking CCI#41 or remington 7 1/2's

I haven't tried all that are available, but CCI450's are the toughest I've used.
You cannot discover new oceans unless you have the courage to lose sight of the shore
Wolf or Tula 223s are made with a harder cup for use in military rifles. They are a bit hotter as well. If you can find them locally they might be worth a try.
I agree on the Wolf primers being hard. I 5000 of them recently for my AR's and they certainly are a harder cup. Great primers and great price from wideners.
CCI nato primers are harder than normal and as hard as the wolf or tula.
jim
are Rem 7 1/2 primers really hard/low sensitivity?
I have had quite a few FTF's with them and the Wolff 12lb spring I installed, CCI 450s have worked great.
Here is a link to some information on primers regarding pressure and cup thickness:

Tula or Wolf have really hard cups. Price is very good as well.
