In the book Shooting The British Double Rifle by Wright you will find lots of loading info. Most of the loads listed for the big cases like the .450#2 N.E. show 4831 powder or RL-15. The info in the book seems to point to powders like 3031 with heavy bullets as occasionally blowing doubles. Most of these bigger cases will need a filler and with out one you will probably have problems, maby even popping a barrel. If you need a filler try foam as was suggested to me by NE450#2 the stuff works great!!
Perhaps the problem with slow powder "blasting" doubles comes as you stated from people using them whitout the filler, and its right that a fast powder will work better in a large case but it also seems that they need more pressure to perform at the same rate. Some slow powder are as i heard a bit funny if the pressure doesent rise fast enough.
I dont think a o/u are stronger but as they are built with the "hinge" as close to the centre of the barrels as possible, the tendancy to open the action is less. On the early days beretta tied the barrels close only with a cloth to show the superior of the construction. Anyway they make an ugly DR.
