I use 2400 for 30 Carbine, 327 Magnum, 357 Magnum and 44 Magnum (1st 3 revolvers and the 44 mag is a carbine). I am starting to run low on 2400 and looking at other options for a substitute until I can get some more 2400. Anyone have a recommendation for a single powder that would cover all 4 of these calibers? I really don't want to add 2 or 3 new powders to my collection if I can help it. Thanks!
