4th page of the owners manual says 33 grain ammo is fine.
It then goes on to mention that 30 grain ammo may fail to cycle due to low chamber pressures particularly if you are shooting limp-wristedly.
No reason whatsoever to suspect that inadequately-pressured ammo should lead to catastrophic (relatively) case head failure!!!
