Hodgdon H335 Spherical Rifle Powder was originally used by the military, specifically the .223 Remington and 5.56 NATO, but today, it remains a popular choice for small cartridges when hunting squirrels, prairie dogs, and other small prey. This powder is an affordable choice for reloading and comes with a solid backing from the manufacturer. This smokeless powder has a fast burn and is easy to meter. The manufacturer provides a warning that loads displayed in the guide should never be exceeded, and at no time should any two different powders be mixed, no matter the brand or type.
