Hodgdon H335 Smokeless Powder - 1lb Can - Hodgdon H335 smokeless powder originated as a military powder for the 5.56 NATO. Rather the 223 Remington as those who load by hand know it. Obviously, it sees endless use in the 222/223 Remington and other small cartridges. In particular, prairie dog shooters will find this a favorite. See the Hodgdon Annual Manual for recommended uses of this powder.
