The current AA data has a variety of loads for different 125gr bullets with a curious split, as the min and max charges vary quite a bit with different bullets. The two highest show a max of 7.8 which mirrors the Speer data. The minimum 357 magnum loads with this same bullet and powder combination are all substantially higher. So I felt safe starting off with 7.8. I won’t be able to try it until next week but will let you know how it turns out.

I did shoot a hundred rounds of my 2400 load last week, which rendered the gun filthy. It was accurate and recoil was authoritative leading me to believe that whoever was on the other end would definitely rue the day, but the gun and bench were sprinkled with unburned powder flakes. I have 150 more rounds of this stuff to get rid of and will never use that load again.

I actually bought eight pounds of 2400 last year because the reloading manual data indicated it was suitably flexible for downloading 357 and 44 to lower-than-max velocities. I have found that once the charge is reduced it no longer works effectively. I guess I can turn up the steam, but that’s why I have eight pounds of WW296?

First world problems....
Mike, FWIW 2400 can be reduced somewhat and still burn at nearly 100 % efficiency. In .357 mag cases I load a bulk 158 gr. JHP on top of 13.5 grs. of 2400, employ a firm roll crimp and use standard primers. It is a 90% full power load and burns clean. If I reduce the powder charge to 12.8 grains I get a modest amount of powder granules in varying stages of burn.
