NOTE: Requires a Minimum 1-10" Twist Meeting all lead-free hunting regulations, Nosler's E-Tip bullet provides exceptional stopping power and peerless penetration over a broad spectrum of impact velocities, rivaling even the highest quality lead-core bullets. Upon impact, Nosler's exclusive EA^2 Cavity [Energy Expansion Cavity] allows for immediate and uniform expansion, yet retains 95% weight for improved penetration. The bullet's boat-tail configuration combined with the streamlined polymer tip assures long-range performance and ease of loading, making it a favorite amongst hand-loaders desiring a lead-free hunting bullet.
