Underwood Ammo's .44 Magnum +P ammunition loaded with 340-grain hard cast flat nose bullets delivers the kind of terminal performance serious handgun hunters and defense-minded shooters demand. The gas check design—a small brass cup at the bullet's base—protects the lead core from hot powder gases and helps maintain consistency, especially critical when you're running a magnum load through a revolver built to handle it. Hard cast bullets resist deformation and penetrate deep, making them the choice for hunting large game or when you need reliable performance through heavy clothing or barriers.
Built for .44 Remington Magnum firearms proofed for +P loads, these rounds bring serious power to the table without the unpredictability of light or inconsistent ammunition. The flat nose profile aids expansion and barrier-blind performance, a design feature long proven in hunting and defensive applications. Whether you're working up loads for a Ruger Super Blackhawk, a modern revolver, or testing handloading recipes, Underwood's quality brass and careful assembly give you ammunition you can trust when it counts.
This case pack includes 10 boxes of 20 rounds each—200 total rounds—so you've got enough to stock up without the hassle of multiple smaller orders. Quality handgun ammunition at this power level isn't everywhere, and consistency matters when you're dealing with magnum pressures.
| Caliber | .44 Remington Magnum +P |
| Bullet Weight | 340 grains |
| Bullet Type | Hard cast flat nose with gas check |
| Rounds per Box | 20 |
| Boxes per Case | 10 |
| Total Rounds per Case | 200 |
Only revolvers and handguns specifically proofed and rated for .44 Magnum +P loads should fire this ammunition. Standard .44 Magnum chambers may not safely handle the increased pressure. Always verify your firearm's marking and manufacturer specifications before shooting any magnum load.
Hard cast bullets penetrate deeper and resist deformation better than softer projectiles, making them ideal for hunting large game or situations where barrier performance matters. They're also commonly used in handloading and can be less expensive than jacketed alternatives.
A gas check is a small brass cup that sits at the base of a cast bullet, protecting the lead core from hot powder gases that would otherwise erode and deform it. This helps maintain velocity consistency and pressure levels, important for reliability and accuracy in handgun loads.
The 340-grain hard cast flat nose design is well-suited to hunting applications where penetration and reliable performance are priorities. Always follow local hunting regulations regarding ammunition type and energy requirements for your quarry.
