All your "specials", .38, 9mm, .44 special, .45 you can (I do) use HP-38/w231 or Bullseye. When loading pretty much anything other than 9mm, be VERY CAREFUL not to double charge as these powders are higher density and do not fill a case,

For the mag loads in .357 and .44 my personal preference is 2400. Great versatility without some of the issue you will find with some of the other mag powders like W296 / H110
