Description
The Buffalo Bore 4H20 brings a unique approach to .44 Magnum ammunition by pairing a lighter-weight 180-grain bullet with velocities high enough to ensure consistent performance. This isn't your standard medium-power load. The medium cast hollow point design expands dramatically upon impact at these velocities while the reduced bullet weight keeps recoil more manageable than heavier alternatives. That matters if you're working with a revolver and need to place follow-up shots under pressure.
What Sets the 4H20 Apart
Buff Bore engineered this load specifically with defensive use in mind, and they've included flash-suppressed powders to cut down muzzle flash in low-light situations. That said, any .44 Magnum round traveling this fast from a typical revolver barrel will still produce visible flash, but it's a noticeable improvement over standard loads. The brass casing is reloadable for those who handload, and the overall build quality reflects Buffalo Bore's reputation for precision manufacturing. People who've tested this round report solid accuracy and consistent performance across different revolver platforms.
Who This Ammunition Fits
The 4H20 works well for anyone running a .44 Magnum or .44 Special revolver who wants a defensive-capable load that won't beat them senseless on recoil. It's frequently chosen for home protection setups in guns like the Ruger Super Blackhawk, Redhawk, and S&W revolvers. The controlled expansion design appeals to folks concerned about barrier performance and shot placement precision. Because of the medium cast construction and expansion characteristics, it's also pulled duty for small to medium game hunting from handguns.

Frequently Asked Questions
What's the advantage of the 180-grain weight over heavier Buffalo Bore .44 Magnum loads?
The lighter 180-grain bullet reduces felt recoil, which helps with faster follow-up shots and easier target re-acquisition in defensive scenarios. It still reaches high enough velocities at 1550 fps to ensure the hollow point expands reliably, giving you a balance between manageable recoil and reliable terminal performance that heavier loads can't match.
Will the 4H20 work safely in .44 Special firearms?
Yes, Buffalo Bore designed this load to be safe in both .44 Magnum and .44 Special firearms in normal operating condition. That extra versatility makes it a solid choice if you own multiple big-bore revolvers, though you'll get the full velocity in the Magnum platform.
How much muzzle flash does this ammunition produce?
The 4H20 uses flash-suppressed powders, which reduces flash compared to standard loads. However, with any round moving at 1550 fps from a typical revolver barrel, expect some visible flash in low-light conditions. It's an improvement over non-suppressed alternatives but won't eliminate flash entirely.
Is this ammunition reloadable?
Yes, the brass casings are reloadable. If you handload, the 4H20 brass is worth saving, though you'll want to follow proper handloading practices and Buffalo Bore's published data for any loads you develop.
