But 231 is also position sensitive, or more correctly, able to get out of reach of the primer flash. Especially if you seat a 125 to 158 OAL and leave even more airspace.

Commercial ammo is not waterproof to sustained exposure by the fire department and probably some rain through the burned through roof.
