Be advised it is a 30 second rule to be safe.Usually on the range they use a 6 second rule with a misfire if it has not gone off in that time its safe, I would just pull the bullet in the press tip out the powder push out the primer and put a new primer in and re load it.
The round must not be re-struck as the primer has been weakened and may burst.
The round is the shooter's responsibility to make safe (dis-assemble usually with an inertia bullet puller).
This is the requirement for misfires recommended by the NRA
