The Underwood 44 Rem Mag +P+ 340 grain load is purpose-built for serious hunting and field use. The 340 grain hard cast bullet with flat nose profile is engineered to drive straight through dense bone and muscle without expanding, which means you get penetration designed to reach vitals on larger game animals regardless of what they're hiding behind.
The real difference here is the Black Cherry polymer coating. This isn't just cosmetic. The coating prevents lead from contacting your bore as the round fires, which virtually eliminates the lead fouling problem you might run into with uncoated cast loads. You get cleaner shooting and less barrel maintenance. The gas check on the bullet helps protect the base against gas cutting when you're running these hotter +P+ pressures.
Flat-nose hard cast design excels at what it was made for: going through obstacles. Unlike expanding bullets that open up on impact, these maintain their shape and nose-forward position, which lets them punch through shoulder plates, dense hides, and bone structure that softer ammunition might struggle with. The 1425 feet per second muzzle velocity and 1533 foot-pounds of energy transfer delivers the momentum needed for larger, tougher game. This isn't ammo for deer at 50 yards; it's made for situations where you need absolute certainty of deep, reliable performance.
The nickel-plated brass cases are new production, non-corrosive, and Boxer-primed, making them reloadable if you're into rolling your own. The quality of the brass and the consistent loading from Underwood means you get reliable ignition and smooth feeding. Each box contains 20 rounds.
The +P+ designation means these rounds generate higher pressure than standard .44 Magnum loads, so you need a firearm specifically rated for +P+ ammunition. This typically includes modern Ruger revolver models like the Super Redhawk, newer Taurus guns in good condition, and specific lever-action rifles designed for hot loads. Always check your firearm's manual or contact the manufacturer before using this ammunition.
The Black Cherry polymer coating on these rounds prevents lead-to-bore contact, which virtually eliminates the lead fouling problem common with uncoated cast bullets. The gas check on the bullet adds another layer of protection, especially important at the higher velocities of +P+ loads. You'll still want to keep your barrel reasonably clean, but fouling should be minimal.
Hard cast flat-nose ammunition like this is purpose-designed for penetration through dense bone and muscle, which makes it better suited for tougher, larger game or situations where you need absolute stopping power. For deer hunting specifically, expanding ammunition or softer lead designs are more efficient, as they deliver shock to vital areas without over-penetrating thin-skinned game.
Yes. The nickel-plated brass cases are Boxer-primed and non-corrosive, which means they're fully reloadable. The nickel plating actually makes reloading easier since it resists tarnishing and provides better corrosion resistance than standard brass during storage or cleaning.
