They gave you the correct answer. From what I've read, ammo makers get their powders in large quantities from the powder makers and then load it to the velocity level they want. The powder is not cannister grade, like we would buy for reloading. Cannister grade means one batch will be the same as the next. This is why we're warned NOT to open up a factory load to copy what they are using. It might look like Red Dot, for example. But it may not be the same as the Red Dot we buy over the counter.
Even before I asked, I knew the answer and why. I was (remotely) hoping that they might at least provide a pressure range (suitably broad for Remington and their lawyers) for the Managed Recoil shells. As it stands, we must believe that there is no pressure difference between Remington's 2 3/4" Managed Recoil loads and their 3 1/2" Premier High Velocity Buffered Magnum Turkey loads. Ask about either shell and you'll get the same canned answer.
