Don't worry, you aren't going to get impact ignition of the primers. It takes a piercing action with a pointed object with velocity (firing pin with released spring tension) to initiate a primer. That won't happen in a tumbler (unless you load it and throw the whole shebang against a wall) and one of the primer ends is perfectly aligned with another meplat and the melpat has to be pointed and hard enough to provide a piercing action...
Highly unlikely.
