Rich knows what I'm up to.  Ve haf ways of turning up the heat!  The only chronograph results I have shows I got the 30H, probably around 180gr, up to 2206fps with no problem.  I really should get me a chronograph before starting on this project.  The whole problem with those 50BMG powders in smaller cases is the difference between a LR primer and a 50BMG primer.  As parashooter said, they (the powders) never get hot enough to burn much before the bullet exits the muzzle.  That's true, unless you turn up the heat.  I'll see how it goes and let you all know.
