Description

The Barnes Pioneer 357 Magnum 140 grain XPB bullets deliver proven all-copper construction for reliable expansion and deep penetration in medium game and personal defense applications. These lead-free projectiles feature Barnes' signature hollow point design that opens consistently across a wide velocity range.

What Makes This Different

Unlike traditional lead-core bullets, the XPB (X-Pistol Bullet) uses 100% copper construction that retains nearly all its weight after impact. This solid copper design eliminates lead fouling in barrels while providing deeper penetration than conventional hollow points. The four-petal expansion pattern creates larger wound channels while maintaining structural integrity through heavy clothing and barriers.

Key Features

100% copper construction eliminates lead exposure and barrel fouling
140 grain weight optimized for 357 Magnum velocities and energy transfer
Hollow point cavity engineered for reliable expansion at 800-1,400 fps
Four-petal design creates consistent wound channels
Near 100% weight retention maintains momentum through barriers
California compliant lead-free construction
Precise manufacturing ensures consistent accuracy and performance

Field testing demonstrates these bullets maintain accuracy comparable to match-grade projectiles while delivering superior terminal performance on medium game from whitetail deer to feral hogs. The copper construction performs consistently in both short-barrel revolvers and carbine-length firearms, making them versatile for hunting, ranch work, and personal protection. Environmental conditions from sub-freezing temperatures to desert heat show minimal impact on expansion characteristics.
