The Underwood Ammo .50 Beowulf 350 Grain Full Metal Jacket is purpose-built ammunition for shooters who demand penetration and power in a big-bore platform. This 50 Beowulf load pairs a 350-grain FMJ-FN (full metal jacket, flat nose) bullet with modern brass cases, delivering the kind of hard-hitting performance that serious hunters and defensive shooters expect from a cartridge designed to stop large, dangerous game. At 1,775 feet per second and 2,449 foot-pounds of muzzle energy, this round hits like a truck and keeps going through what's in front of it.
The flat-nose bullet design is the key difference here. Unlike traditional round-nose non-expanding bullets, the flat nose maintains its orientation as it penetrates, allowing the full frontal surface to work through dense material—thick hide, heavy bone, brush—without deflecting. That nose-forward stability is critical when you're counting on a round to perform under real-world conditions. Underwood uses a copper-lead construction for reliable performance, and the FMJ design ensures the bullet stays together and drives deep, which is exactly what you want in a woods-defense or hunting scenario.
This is new production ammunition, loaded into reloadable brass cases with Boxer primers, so you can reload once you've fired them. The round is non-corrosive and safe to use in suppressed rifles, giving you flexibility in how you set up your platform. Each box contains 20 rounds, and the case quantity lets you stock up on a cartridge that doesn't sit on every shelf. If you run a .50 Beowulf and you're serious about terminal ballistics, this load deserves a hard look.
