  Did you get a chronograph reading on the shot that caused the blow-up? If so, how did it compare to the previous readings?
  
  
  Did the chronograph get a reading?
  
  I suspect double charge of powder! (the factory cautions about double loads when using 5744)
  
  I've used 5744 in several rifles of several calibers, for example 30-06, 7mm Rem mag, 7mm WBY magnum, 270, 223's for reduced loads, reduced recoil for several years. (the reduced load data for 5744 that I use comes from reloading manuals or factory recommendations)
  I'm very careful and keep a heads up alert, knowing that a double charge could be easily overlooked until the trigger is pulled!The 223's are very accurate to 75 yards reduced loads are used at 22 mag velocities and 22 mag sound levels for squirrel hunting. (can use same gun at high velocities for varmits (coyotes) and low velocities for squirrel hunting)
  
  On my regular Hunting rifle loads I start testing and normally select powders that fill the case to 80% or more for at least two reasons, first usually the most consistently accuracy is found with the slower burning powders and also lessens the chance of a double charge!

  I agree, that is a TON of gas venting down the magazine well. The OP has stated that the chrono gave 3 readings for the 3 prior rounds,..so I guess we can eliminate a bore obstruction.
  
  All I can figure is,....
  1. double charge
  2. detonation
  3. oversized projectile
  
  
  You cannot eliminate bore obstruction, unless you know for sure the bullet the shooter was using, was not gas checked. We do know, if I remember the original post correctly, that these were reduced loads with lead bullets. Being a rifle, of moderate velocity for lead loads, it most likely had a gas check. The gas check could have, fell off and obstructed the bore, while the rest of the bullet, went on to exit the barrel, and cross the chronograph. Seen it happen before in a friends Colt Python.

  A few months ago, I asked if anyone had blown up a Vanguard because I said you could look through the bolt raceways from the back of the gun and see the back of the barrel.
  
  In other words, there's no gas shroud like the cocking piece of a Mauser has.
  
  Maybe the Weatherby corporation surreptitiously decided to test one to destruction for us to dispel any doubt my posts on the topic may have caused?[;)]
