   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?

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

   The powder arrived very quickly and well packaged. I use this for .357 loads. I load 125gr JHP, which makes for some real hotsteppers. The powder arrived very quickly!

   Trying to get consistent loading info for 454 Casull can be frustrating, but it is out there. Using 4227 with 300gr cast bullets in a RIFLE. (Loading tables are all for pistols) But I am getting 1300 fps and 3″ groups @100yds with hopes to make it tighter next spring. 4227 leaves a lot of unburned powder in a rifle barrel. I hope someone comes out with 454 rifle data soon.
