Barnes Bullets Spit-Fire TMZ Muzzleloader 50 Cal 290gr 24/Bx

The Barnes Bullets Spit-Fire TMZ is a high-performance, saboted hunting projectile designed for 50 caliber muzzleloaders. Built on a 100% copper body with a precision-molded polymer tip, this boat-tail bullet is engineered to deliver reliable expansion starting at just 1050 fps while retaining weight for deep penetration on big game.

Each 290 grain projectile measures .451" in diameter and is designed for use with a sabot in 50 caliber muzzleloader barrels. The boat-tail base and recommended 1:16" twist rate produce a flat, accurate trajectory, with a published G1 ballistic coefficient of 0.241 and sectional density of 0.204. Typical loaded muzzle velocities range from 2000 to 2400 fps depending on powder charge and seating depth.

These lead-free bullets load easily even in tight or fouled bores, making them a strong choice for muzzleloader hunters pursuing big game and medium game in areas requiring non-toxic projectiles. The polymer tip initiates reliable expansion across a wide velocity window, while the copper boat-tail base supports efficient flight. 24 bullets per box, current production from Barnes Bullets.
