Don't know if this is a very good test, but I recently shot about 400 that were about 20 years old and didn't have one that failed to go bang.
I need to add that these were not stored in any specific way to preserve them. They were hand loads also, and to tell the truth they "felt" a little "hot" compared to normal.
