Description
Big Game is a versatile rifle propellant manufactured by Ramshot, known within the handloading community for its medium burn rate, making it suitable for a variety of mid-sized rifle calibers. This powder is a popular choice for applications including cartridges like the .308 Winchester, .270 Winchester, and .30-06 Springfield. It is a double-base, spherical powder, ensuring excellent metering properties that allow for precise and consistent drops, essential for high-volume reloaders striving for repeatable performance. One of the standout characteristics of Big Game is its temperature stability, providing consistent velocities across a wide temperature range, which is particularly advantageous for hunters and competitive shooters who may encounter varying environmental conditions. When developing loads, users will appreciate its manageable pressure levels, offering a forgiving margin for slightly hotter loads when necessary. Ramshot's commitment to quality and performance, backed by a solid reputation among handloaders, ensures that Big Game meets the needs of those seeking reliable and accurate rifle cartridge performance.
