Description
Buffalo Bore's Heavy .44 Magnum load steps up to a serious 300-grain semi-jacketed flat point projectile, giving you ammunition that means business when you need maximum terminal performance. Built on reloadable brass, this load delivers approximately 1300 fps and 1126 ft-lbs of muzzle energy, keeping the flat point design working exactly as intended at handgun speeds.
What makes this 300 grain load different
The semi-jacketed flat point bullet is specifically engineered for deep penetration without relying on expansion. That flat profile does exactly what it was designed to do at revolver velocities, punching through heavy bone and muscle with the kind of straight-line performance that made flat point designs a go-to choice. Field testing shows you can expect around three feet of penetration through muscle and bone when fired from a revolver, while the design still delivers terminal performance if used in a lever-action rifle, though with less penetration depth.
Consistent velocity and reloadable brass
Every round leaving the box has gone through Buffalo Bore's quality control process, delivering the velocity and energy ratings you see on the box. The brass cases are reloadable, which means if you want to roll your own, you've got years of shooting ahead with these cases. That matters whether you're running a Ruger Redhawk, Anaconda, or any other quality revolver that can handle this kind of power.
This isn't entry-level ammunition. It's purpose-built for people who know exactly what they need from their .44 Magnum and aren't settling for compromises.

Frequently Asked Questions
Will Buffalo Bore 300 grain .44 Magnum work in my revolver?
Buffalo Bore loads this ammunition to standard pressures for typical .44 Magnum revolvers, but this is a heavy load. Ruger single-actions and other quality firearms designed for full-power .44 Magnum rounds handle it without issue. If you own a Smith & Wesson or older revolver, check your manual first, as some manufacturers have specific limitations on bullet weight.
What's the difference between semi-jacketed flat point and other bullet types?
The semi-jacketed flat point keeps a lead core partially exposed at the tip, which helps maintain the flat point profile through impact. This design prioritizes penetration over expansion at handgun velocities. You get straight-line tissue destruction rather than a blooming effect, which is exactly what this load was built for.
Can I reload these brass cases?
Yes. Buffalo Bore uses quality brass with Boxer primers, so they're set up for reloading. Many people reload these cases multiple times before any signs of wear show up, making them a good value if you're into handloading.
How does this perform in a lever-action rifle versus a revolver?
Fired from a rifle, this load will exceed the velocity targets and the bullet will expand more than it would at handgun speeds, resulting in less penetration depth overall. Buffalo Bore designed this specifically for revolver velocities, so revolver performance is where you get the intended ballistics.
