No properly designed rifle should fire out of battery with any ammo of the right caliber. That's why there are SAAMI specs. If a hollow point bullet causes it to get hung up during feeding then it should only jam not fire. This might seem like no big deal because it's just 22 rounds blowing up and a few rifles going back to the factory, but imagine if this were 223 rifles firing OOB. A recall may be in order once they collect enough data from returned rifles and find a fix.
