I know I'm straying OT, but since you brought it up:
4227 does well for reduced loads in the big cylindrical cases too, 444, 45/70-90, 458, etc.
For example in 444 a 240 jacketed would be over 46-47 gr 4198 for 2300-2400 fps.
31-35 gr 4227 gives 1950-2150 fps.
Much easier shooting.
IMR4227 is one of my all time favorite powders.
