Accurate Ramshot Magnum Smokeless Rifle Powder 1 lb Canister

The Accurate Ramshot Magnum delivers consistent velocities and tight groups for high-performance rifle cartridges. This temperature-stable powder excels with heavy bullets in magnum calibers, providing the energy density needed for long-range precision shooting. Manufactured using advanced spherical propellant technology, it meters uniformly through powder measures for reliable charge weights.

What Makes This Different

Ramshot Magnum utilizes Western Powders' proprietary spherical grain structure that flows smoothly through powder dispensers without bridging or clumping. The temperature-stable formulation maintains consistent burn rates across extreme weather conditions, from sub-zero hunting trips to desert competitions. This powder generates higher velocities than many stick powders while producing lower pressure spikes, extending brass life and improving accuracy potential.

Key Features

• Temperature-stable formulation maintains consistent performance from -40°F to 140°F
• Spherical grain structure meters precisely through all powder measure types
• Optimized for magnum rifle cartridges from .264 Win Mag to .338 Lapua
• Low copper fouling characteristics reduce barrel cleaning frequency
• Produces excellent velocity consistency with heavy bullets (180+ grains)
• 1-pound canister provides approximately 140-160 loads depending on cartridge
• Manufactured in Belgium using Western Powders quality standards

Field testing demonstrates exceptional performance in popular magnum cartridges including 7mm Rem Mag, .300 Win Mag, and .338 Win Mag. The powder's burn rate positions it ideally for heavy-for-caliber bullets in long-range hunting and precision rifle applications. Competitive shooters report velocity standard deviations under 15 fps when used with quality brass and consistent loading techniques. The low flash signature reduces muzzle blast visibility during dawn and dusk hunting conditions.
