As others have said, 3-5% is incredibly high, even for bulk ammo. If you're getting that with CCI, and the rate of failure isn't significantly different between CCI and cheapo bulk ammo, there's probably a problem with your guns. The common issues that I've seen are a dirty firing pin channel resulting in the pin dragging, a trigger overtravel screw adjusted too tightly such that it results in the sear dragging, and modifications like significantly lightened hammers and springs. If you buy some match ammo, don't buy the green Remington stuff. It's incredibly unreliable. The brands suggested by other people here are great. Nonetheless, there's no way CCI is consistently getting 3-5% failures.
