Ever so often, someone will post a message including the information that CCI Primers are relatively tough and require a stronger firing pin impact and that Federal Primers are relatively soft and will go off with less impact.
Here lately it has become popular to deny that there are any hard/thick- soft/thin primers; say that they are all the same and frequently call the poster a ass a idiot for being so stupid.
Experienced reloaders who have had occasion to use different primers and handguns with marginal firing pin impact have long known that loads using CCI primers are more prone to soft impact failures to fire than the same loads using other primers. This is dedicated to those reloaders who are tired of being called idiots by...... idiots:
I started out with primed cases and an enclosed hammer .38 s&w "Owlhead"
that has a fairly moderate firing pin impact. It is totally ignition reliable with Peters factory loads. I primed three cases each with CCI small pistol primers and Federal Small Pistol primers. The dints on the CCI were markedly lighter than those on the federals and one of three of the CCIs failed to fire.
I then loaded up 15 each .357s using CCI and then Federal Primers. The GP100 I used has an adequate double action hammer fall and there were no misfires with either primer. The primers were seated on the same machinery during the same loading session. The firing pin signature and the overall flattening of the fired primers is quite a bit different with the two brands of primer.
