Here's my warning and advice on that........
Many people buy the 650 to make ammo FASTER. The primers will explode if you slam them fast into the primer pockets, especially if one gets sideways in the primer fill tube.
FAST ammo is NOT GOOD AMMO. I suggest that you slow down, and be more careful. DO NOT SLAM the primers into place.
I have never had a stack of primers explode like that. Tens of thousands of reloads. Never even had a single one explode in a single station press. If you go slow you can fold primers in half and they will not go bang.
Think of how a primer is designed. Firing pin hits it with speed, and force of speed. It takes both to make it burn. By going too fast, you are simulating the action of the firing pin, hard and fast. So, slow. Don't try to get 650 9mm's per hour, or 800 or 1000 per hour. That's not going to be good ammo, and could cause the type of explosion you incurred.
When I do my reloading classes, on a single station press, I always watch for students to start getting lazy, and slam the primers into place. I always stop them, remind them about the firing pin example, and allow them to continue, slow pressure to place the primers in the primer pocket.
I doubt that the chain reaction had anything to dob with the maker of the primers, bad batch, or anything like that.
