I guess when it comes to what ammo I really trust, it is my reloads. I have been reloading for 48 years and have never had a fail to fire. In my current pistol ammo that I load most of, I have 2 Ruger P97's, a P90, and a P345 that I reload Ball and Hollow point ammo for and they all work well with it. If ammo is loaded right, it won't cause jams or misfires. Those are mechanical problems with the gun or shooter.
