Description
Accurate MAGPRO is a slow-burning rifle propellant with a burn rate of 0.5, designed specifically for magnum rifle cartridges. This double-base powder is well-suited for achieving high velocities in large case capacities, making it an ideal choice for calibers such as 7mm Remington Magnum, .300 Winchester Magnum, and .338 Lapua Magnum. MAGPRO features a spherical grain structure that ensures consistent metering through powder measures, enabling precise charge weights ideal for long-range shooting applications. Handloaders will appreciate MAGPRO's temperature stability, which provides consistent performance across varying environmental conditions, reducing variations in muzzle velocity that could impact accuracy. When developing loads with MAGPRO, it is essential to begin with published data, carefully adjusting for case capacity and primer selection to optimize ballistic performance. Due to its slow burn rate, it is important to ensure proper case fill and ignition, commonly achieved with magnum primers. MAGPRO's reputation for delivering top-notch performance in high-pressure magnum calibers makes it a staple among serious rifle handloaders seeking maximum accuracy and velocity.
