Buffalo Bore 9B20 444 Marlin 300gr SJFP Heavy Load - 20 Rounds

The Buffalo Bore 9B20 Heavy Strictly Business load transforms the 444 Marlin into a true big game powerhouse. This premium ammunition delivers substantially more energy than factory loads while maintaining safe pressure levels in quality firearms. Buffalo Bore's reputation for maximum performance ammunition makes this load the choice for serious hunters pursuing dangerous game.

What Makes This Different

This heavy 444 Marlin load pushes a 300-grain semi-jacketed flat point bullet at velocities that exceed standard factory ammunition by 200-300 fps. The semi-jacketed flat point design ensures devastating terminal performance on large game while the flat point aids in tubular magazine feeding. Buffalo Bore uses premium components and precise powder charges to achieve maximum velocity while staying within SAAMI pressure specifications.

Key Features

• 300-grain semi-jacketed flat point bullet for deep penetration and expansion
• Significantly higher velocity than standard 444 Marlin factory loads
• Flat point design optimized for lever-action tubular magazines
• Premium brass cases suitable for reloading
• Temperature-stable powder for consistent performance
• Quality control tested for accuracy and reliability
• 20 rounds per box, 12 boxes per case configuration

Field performance demonstrates this load's capability on elk, moose, and bear-sized game where deep penetration is essential. The semi-jacketed construction provides controlled expansion while retaining enough bullet weight for complete pass-throughs on heavy-boned animals. Hunters report excellent accuracy from quality lever-action rifles, with many achieving sub-2 MOA groups at hunting distances. The flat point design feeds reliably in tubular magazines while providing better ballistic coefficient than traditional round nose bullets.
