Interesting, what I found really interesting was searching info on it, leading to a Euro reloading site that has some interesting info, some of which is free and some which isn't. Check out XXL Reloading in your travels. I am always searching 30R Blaser data, they have some there in their protected stuff, just a matter if I feel like paying 10.00 to see what they have there.
One thing on that site is a fairly new powder burn rate chart, with the bulk of the newer powders on it from Europe.And some cartridges you may not expect to see. The data on the 8.5x55 tells a lot about it, it's a .338x55 that seems to get decent speeds.
