I feel the hardest is the WOLF primer. Next I feel would be CCI.

I had some CCI? military pistol primers once if my memory is still good. They were very hard. Would reliably run through one of my 1911s but not the other that had the really nice 3.5# trigger. Both worked fine with commercial ones. I have seen them for sale intermittantly. I have some small rifle military primers from CCI and some from Winchester somewhere in my large pile of stuff.

During the early part of the current primer shortage we had some SASS shooters buy the Wolf brand and they were having several FTF on each cylinder. These revolvers were modified for competition and not stock. The same guns have no problems with Winchester or Federal. In order of hard to soft I would go Wolf, CCI, Win, R-P, and Federal

Probably **** built up in the primer pocket. CCI is the hardest primer made

CCI is much harder than Remington or Winchester. Federal is the lightest of all. I know nothing about Wolff, except that the guys I shoot with who had to resort to them during the market turmoil of the past year had lots and lots of light strikes with them. So, they must be hard also (or, just crappy). I do not know where they stand in relation to the CCI, which is notorious for its hardness among action shooter with race gunz.

Indents made in primers with a Lee Hardness Tester- the size of the indent from a 5/8" ball with 60 psi of the Lee Tester:
0.32 – CCI 300 LP
0.34 – Remington 9 ½ 6% - softer than CCI
0.40 – Winchester WLP – 25% softer than CCI
0.42 – Federal 150 LP – 31% softer than CCI

Haven't measured, but presume the other LR's are the same hardness
