Thanks for that, but what I'm trying to arrive at isn't the maximum possible loads, but a comparison of reasonable working loads (similar pressures for both cartridges) such as the military might choose for a "vanilla" ball round, comparing a Grendel from a 24 inch barrel with a Creedmore firing the same bullet from a 16 inch barrel. The purpose is to illustrate the benefits of long barrels (as in bullpups) in enabling smaller and lighter ammunition to be used.
