oh, wow, that's a huge number of misfires. I've never had a primer misfire, except one time when I accidentally primed a bunch of shells that were still wet inside from when I washed them...
In my experience, no modern primer should misfire, provided your firing pin is in good shape & the primers have been stored correctly. Hell, I've fired 50 year old foreign milsurp ammo without misfire. Of course, if you use large pistol primers in rifle brass, or vice versa you might have problems. And if you are loading large magnum cases with large charges of slow ball-type powder, you may also need magnum primers to ensure reliable ignition.
