what powders are you using?

The subject of this thread is the powders that work well in the 300-221 Fireball aka 300 Whispler. I have reloaded the following powders

Hodgdon Lil-Gun
Hodgdon H-110
Alliant Reloader 7
Accurate Arms #9
Hodgdon H4227
Winchester 296

For super sonic loads, I have found W296 to produce the tightest groups (<1.0-inch at 100 yrds) and pretty good velocities. I consistently get the top velocities with Hodgdon Lil'Gun but the groups tend to run ~1.0-inch at 100 yrds. I get the best groups (<0.7-inch at 100 yrds)with AA#9 but the velocities are only modest.

For sub-sonic loads, I have found AA#9 to be one of the best... tight groups and very consistent velocities even with pretty large temp. changes.

I would like to try the following powders

Alliant 2400
vihtavuori N-110
Accurate 1680

I would like to hear about peoples experience with these as well as other powders including the one I have listed.

My reloading data is posted here:

http://reloadersnest.com/frontpage.asp?CaliberID=135

The loads listed under "Not yet verified user loads" are the one that I have shot with the exception of loads#:
2973
2974
3299
3577

Most of thse loads were shot and chronographed at an indoor range so the temps at the tme were 70 F +/- 3. The elevation here is ~240 ft.
