Exergy (XRG)

Hunting

Exergy (XRG) bullets are lead-free, expanding projectiles typically made from solid copper or copper alloy. Designed for hunting in regions with lead ammunition restrictions, XRG bullets offer reliable expansion and deep penetration similar to traditional lead-core bullets. The monolithic construction ensures 100% weight retention—nothing separates or fragments. Various manufacturers produce XRG-style bullets under different names; the term has become somewhat generic for lead-free expanding hunting bullets. They're particularly popular in European markets where lead restrictions are more common.

FAQ

Why choose lead-free hunting bullets?

Legal compliance in lead-free zones (California condor areas, some European regions), reduced environmental impact, and excellent terminal performance from 100% weight retention. Many hunters choose lead-free even where not required for these benefits.

Do lead-free bullets perform as well as lead-core?

Yes, modern lead-free bullets like XRG perform excellently. The 100% weight retention often means deeper penetration than lead-core bullets that may fragment. Accuracy is comparable to premium lead-core bullets.
