I wonder if these recent blowups have occurred due to detonation. Seems most if not all of these that were not the result of an obstruction were "lite" or reduced load reloads. Detonation occurs when there is too much space in the powder compartment and the powder burns instantaneously instead of progressively causing a huge pressure spike. It seems feasible that the wad in these reduced loads is not compressing the powder adequately?
Just a thought.
