The original full power load that Elmer Keith developed for the 44 mag, was 22 grains of 2400, with the bullet he developed for it, a cast semi-wadcutter of about 240 grains, though my bullets from the Lyman mold for it were often over 250 grains.
22 of 2400 is usually considered the same power as 24 grains of H110/296, but the 2400 develops a bit more vel.
I used a lot of the old surplus powder that Hodgdon's hung the handle of H110 on and the same rules apply to using it in the 357, as the 44 mag.
Nothing was printed about H110 not being suitable for lighter loads, so those of us who used it, often cut the revolver loads down considerably, with pretty good results.
I found the 357 revolver didn't have enough oomph to knock down the rams at 200 meters, so when I was shooting silhouette I cut the 44 mag from full power of 22 grains down to 20 grains of 2400 and was happy with it. It was easier to shoot, knocked the 200 meter rams down, plus only needed one more click of elevation at 2oo, than was required with full house loads of 22 of 2400.
