The Rocky Mountain Warhead SS features a precision-machined compact stainless steel ferrule with a 1.5-inch cutting diameter and a hybrid-tip design that cuts on contact, yet has the strength to bust through bone. The durable 0.035-inch-thick stainless steel blades are securely held in place during flight and reliably jackknife open on contact to administer huge wounds and excellent blood trails. Available in 100 grains for both vertical and crossbows.
