IMR4227 is the best powder for the 357 Herrett especially with jacketed bullets in the 180 to 200 grain weights.

Loading data not listing calibers that were used iin several world wars
Not listing the .303 British rifle caliber for powders that are commonly used is a real disappointment. .303 British caliber with lead bullets like the Lyman 200 grain that is very popular and it is a wonder why it is not listed but something 6.5 Creedmore is. How many British .303 rifles are in the hands of shooters the world over compared to the 6.5 calibers?
