I thing that .400 not it's CIP status yet, but the maximum operating pressures are said to be 4300 bar as in .375 H&H. However, the warranted velocity of 2375 can be obtained wiht noticeably less pressure.

I used this load for the test cartridges:

- QC case
- Fed Gold Medal 215 Match primers
- 400 gr. Woodleigh Soft Point
- 80 gr. Hodgdon 414
- OAL 3.54"

This generates healthy pressures and should provide the needed velocity. I'll work on this afterwards a bit more. I will also work up loads for .405 bullets that would simulate those energy an velocity levels.

Talking about A-Square, I have liked the idea behind .495 A-Square as it has this "ghost shoulder" that makes it easier for the handloader. Have to take a look at the .400 ASDPM too...
