My plan was to use the books for only a basis for powder recommendation. I plan to ignore the upper limits and work off of velocities and pressure signs. It's not an ideal situation, but it'll work fine.
I also have a subscription to loaddata.com, which may have data not contained in the standard manuals. I just bought some H335 today (haven't found any Alliant 10X in a store yet), and still need to order some bullets online. The two stores I've been in haven't stocked a bullet fully appropriate to the 6.8 SPC.
Even if I don't reach the capabilities of the cartridge, It'll far surpass anything the 5.56 is capable of achieving.
Forgot to add, I'm a member of the 6.8 forum, but haven't spent very much time there.........yet.
