The Black Hills Gold 7mm Remington Magnum 139gr GMX delivers lead-free hunting performance with Black Hills' renowned precision loading. At 3,200 fps with 3,160 ft-lbs of muzzle energy, this is among the fastest factory loads available in 7mm Rem Mag. The Hornady GMX bullet is a monolithic copper alloy design that expands reliably while retaining virtually 100% of its weight for deep penetration, regardless of impact angle.

This ammunition excels for hunters who need high velocity and lead-free construction for California and other regulated areas. The blazing speed creates an exceptionally flat trajectory, minimizing holdover requirements at typical hunting distances. Black Hills' hand-loaded quality ensures the consistency needed for precision shooting, while the GMX design handles elk and deer effectively with proper shot placement.

The GMX's all-copper construction prevents lead fragmentation, making it ideal for hunters who process their own game or are concerned about lead contamination in meat. The lighter 139-grain weight maximizes velocity while providing adequate penetration for most big game hunting scenarios. For hunters who want environmentally-conscious ammunition without sacrificing performance, the GMX offers lead-free terminal performance in a precision-loaded package.
