Underwood Ammo
Underwood Ammo Controlled Chaos Rifle ammunition in 350 Legend delivers purpose-built performance for hunters and shooters who demand reliable, modern ballistics. This 150-grain copper hollow-point round launches at 2450 fps with 1999 ft-lbs of muzzle energy—making it a serious contender for medium-game hunting and defensive applications where shot placement and terminal performance matter. Built on nickel-plated brass cases with Boxer primers, every box of 20 rounds is loaded to consistent specifications and reloadable, so handloaders get a second life out of brass they'll want to keep.
The 350 Legend has carved out a niche as a modern, effective cartridge for AR-platform rifles and lever guns, and Underwood's Controlled Chaos load makes smart engineering choices. The copper hollow-point bullet is lead-free, which matters in lead-sensitive hunting areas and ranges. At a sectional density of 0.170 and a ballistic coefficient of 0.179 (G1), this projectile is designed to penetrate reliably and maintain velocity downrange. The round is supersonic, meaning it retains energy and won't lose effectiveness in suppressed rifles—making it safe and practical if you run a can.
Non-corrosive, reloadable brass ammunition from Underwood is manufactured to exacting standards, and this load represents a pragmatic balance between velocity, bullet construction, and terminal effect. Whether you're loading up for a fall hunt, ringing steel at distance, or stocking reliable ammo for home defense, this is working ammunition built by people who shoot.
