Nosler E-Tip 22 Caliber .224 55 GR Spitzer 50 Box. 224 55 GR Spitzer 50 Box - The Nosler E-Tip bullet is a lead-free monolithic copper-alloy .22-caliber boat-tail bullet designed to meet "no-lead" restrictions at many state local and private ranges. It is machined from a high strength copper alloy and features an ogive design with a green polymer tip to initiate expansion. The projectile features an E2 Cavity for amazing stopping power and peerless performance. Because the powder charge is contained within the bullet's hollowpoint cavity the projectile will not decaliber at extreme velocities. Nosler's unique four-petal design will not blow the petals off at any velocity. The boat tail design allows the projectile to climb and maintain an efficient flight path over a broad spectrum of impact velocities making it a great choice for a variety of target shooting applications. Made from Nosler solid copper alloy the E-Tip is designed to meet SAAMI standards for anything .22 caliber or larger. Nosler E-Tip bullets are machined with a hardened form-fitted jacket without any hollow point cores. The polycarbonate tip initiates expansion and preserves 95percent of the projectile's weight.
