No, but you can work it out from the expansion and the muzzle pressure, which are provided. Obviously it will be different for every combination of powder charge and bullet and chambering and barrel length. The other caveat is that the gas is still pretty hot when it gets to the muzzle and will reduces in volume substantially as it cools. That temperature will have to be guessed at, but the ratio of peak to muzzle pressure can probably be applied to the estimated peak temperature of 4500 to 5000 degrees to get a very rough ballpark figure. But a suppressor begins to see gas while it's still hot, anyway, and cools as it expands through the baffles, so this is a complex dynamic problem.


Detonation velocity is the speed of a blasting cap initiated compression wave sustained through a solid piece of a high explosive while it is detonating. Since we carefully avoid detonation in favor of much slower controlled deflagration of gun powder in firearm chambers, it isn't apparent to me what use you have in mind for that detonation velocity information. Is it something specific or just an aside?
