I have been searching for recipes for .357 and .44 Mag with Alliant Pro 300-MP powder. Is 300-MP the same powder as Hodgdon H-110?
As you can see from the picture it is virtually impossible to tell them apart visually and the few reloading recipes I have found are pretty close to the same.
H-110 on the left and pro 300-MP on the right.
