My experience is limited to about 20,000 rounds loaded. Of that, I think I've used 2-3,000 Winchester, 1-2,000 Wolf and I believe the rest have been CCI. The ONLY loads I have that routinely fail to fire are Wolf and Winchester primed loads. It is as predictable as can be.
Both brands consistently cause me problems during the loading process--problems I have never experienced even once with CCI. Both are difficult to seat and both tend to jam up my primer shuttle. Often, they seat just enough to allow the shellplate to start rotating, but not enough to allow it to rotate freely--I then have to fight to get the case over the primer plunger to force it home.
For the Wolfs, I'd say the failure rate for me is about 2-3%, and for the Winchesters maybe half that.
These are all large pistol and all in 45ACP, 10% in a Lee Turret Classic, 90% in Hornady LnL. I've had several folks say they use Wolfs almost exclusively and never have any problems at all, and I expect even more folks use Winchesters with no problems. For me, it is so certain I'll have misfires, I don't buy them. The Wolfs have been significantly worse than the Winchesters though, but both seem very tight in the brass I use--which includes about 7 brands of used range brass.
In shooting some stuff I loaded a year ago, if I open a box and see brass primers (as opposed to nickel finished), I know I'm in for some malfunction drills.
