Winchester Ammunition is taking varmint hunting to a new level, using fragmenting copper core technology to incorporate a lead-free .223 Remington bullet in the Ballistic Silvertip line.  The round features a 35 grain projectile, and plastic tip to reduce tip damage and promote long-range performance.  The fragmenting copper core is engineered to explode on impact.  “The technology behind this bullet is evident on impact,” said Brett Flaugher, vice president of domestic and international marketing and sales.  “Winchester and Nosler continue to work together and offer the most innovative ammunition, and this bullet will clearly stand out in 2010.”  www.winchester.com.
