The photo below has a throat similar except it's not a bottle necked case but the lead is close and it will hold it's own for accuracy.

With all due respect, the 8 X 56 RD is, and was designed as a smokeless cartridge, and the pressure curve there is going to be hard put to provide the "bullet bump / slug up" that sorta' throating calls out.

At this point BP is WELL worth trying, and it would be no big deal to equip that rifle with a wiping rod, for field cleaning.
