The guys are correct. By all indications it is the gun. The firing pin, weaker spring or tolerance of the firing pin travel is different on it that is my bet. Shoot one or two of your good rounds through it. And then two of the bad ones that will fire. Then compare the depth of the firing pin strike in the primers. If it is that much of an issue you can probably visually tell the difference just by looking. The bad rounds should have a shallower strike caused by the primers being a little or a lot harder, or one of the above issues. The good rounds should have a deeper strike on the primer. A gunsmith can fix this for you very easily. I do not know what kind of customer service the company itself has. But if they in the USA or have a service center I would contact them regarding the problem first. Only some ideas and things to diagnose the problem as the others have hit it dead on also.
