Here is more load data for the 25-223Ar. I had a chance to try Hodgdon H335 today. It seems to be the best powder I have tried so far.
Load Data: (standard disclaimer as with any wild-cat, use at own risk and work up slow)
Hodgdon H335, Speer 100 gr SPBT (16 inch 1:10 twist barrel)
Charge
wt.(g)-------vel. (fps)
24.8---------2460
25.7---------2560
25.9---------2581
26.1---------2604
26.5---------2624
I hope this helps

I am running the gun with the gas port turned off to see how it runs before I the port in. Here are some new results.

The Powley pressure calculator (found here: http://kwk.us/powley.html) indicates that the 22.0 g load is generating about 50000 CUP. One might be able to get another 50 fps out of this load.
