Wolf primers appear to be as soft as Federals? Are you serious? I'm not calling you a liar, I'm genuinely curious. It would seem to me they should spec closer to CCI in the hardness dept given what they prime commercially.
I know you weren't talking to me, but I finally wanted to update my thoughts on Wolf primers including on this point.
My initial review was that Wolf primers seemed identical to the CCI and Winchester ones I was using. I'd like to correct that- I am convinced now after a year or so of using them, that Wolf SP primers are at least as "hard" if not harder than "CCI" or Winchester.
I can't put numbers on this "hardness", but I have noticed one thing since I started using Wolf primers. Until I started using Wolf primers, I never had light primer strikes or misfires with any type of my reloaded ammo, using Federal, Winchester, and CCI primers. I began to have misfires / light strikes once I started using the Wolf SP primers for my 9mm and 40. These always fire the second time, but... the misfire rate was around 1-2%, that is maybe one every box of 50. (based on getting one or two misfires in a typical club IDPA match). The problem was worst in my Kahr CW9, which could not set off some of my Wolf-primered loads no matter how many times I tried. The same "failed" rounds would go off just fine in my G19 so I'm convinced it's hard primers.
I wouldn't say I won't buy Wolf SP primers again, I will gladly if that's all I can get. However the experience of the past year has made me stock up on Winchester and CCI primers when I can get them (not easy around here!) I don't have enough data on the other types of Wolf primers (SR, LR, LP) to be able to tell, but I don't recall having this happen with my 45s or any of my rifles. I would imagine these other Wolf primers would be "hard" as well but I don't shoot nearly as much of the other stuff as I do 9 and 40, hence less data.
As always, YMMV.
