Barnes Harvest Collection .450 Bushmaster 260gr Sierra Pro-Hunter 20rd

The Barnes Harvest Collection 450 Bushmaster 260-grain Sierra Pro-Hunter is the heavyweight champion of the straight-wall hunting world. Designed for those who need "Big Bore" authority in restricted zones, it solves the two biggest headaches of the 450 Bushmaster: unreliable feeding and bullet failure. While many brands "cheat" by using soft handgun bullets that fall apart at rifle speeds, this load is purpose-built to cycle flawlessly and deliver the massive knockdown power needed for hogs, bears, and trophy-class whitetail.

The fatal flaw of standard big-bore ammo is the use of repurposed pistol projectiles that "pancake" or fragment on impact. Barnes fixes this by pairing a specialized 260-grain Sierra Pro-Hunter with the high-velocity window of the 450 Bushmaster. Featuring a custom-tapered jacket and a hardened lead core, this bullet is "tuned" to hold together through bone and heavy muscle. You get the devastating initial expansion Sierra is famous for, backed by the deep, internal penetration required for a clean, ethical harvest on large-bodied game.

In the field, success is measured by raw energy and absolute reliability. Traveling at 2,165 fps, this heavy-hitter produces a staggering 2,704 ft-lbs of muzzle energy—more than enough to handle the toughest brush hunts. The precision flat-nose geometry isn't just for impact; it’s engineered to correct the steep feed angles of AR-platform magazines, ensuring your follow-up shots are as reliable as your first. It’s a high-payload, low-compromise system that turns your straight-wall rifle into a true woods-ready sledgehammer.
