For ammo with Nosler Ballistic Tips opt for Winchester Ballistic Silvertip Centerfire Rifle Ammunition. This ammo is able to offer extremely long-range performance due to these ballistic tips. To help maximize accuracy even at a long range there is a polymer tip base boat tail design and a special jacket with contours. The core is made of lead-alloy to help with weight retention as well as penetration. You can select the caliber you prefer and based on this you will have either rapid or controlled penetration and expansion with rapid fragmentation occurring at the smaller calibers.
