Very interesting, thank you. If what I've read is accurate, your most promising loads are No 4 and No 9. For No 4 it's an issue of just tweaking the seating depth. It looks like No 9 is already there, albeit with a bit of pressure signs.
"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
