Winchester was at the 2013 SHOT Show in Las Vegas for the launch of their new Varmint X ammunition line, which is designed specifically with the predator hunter in mind. The new Varmint X is built with a polymer tip and a thin jacket for rapid expansion. This makes the bullet extremely devastating while also limiting pelt damage. Winchester also employs a brass shell casing to help keep the cost down. The new Varmint X is currently shipping in .223 Rem. and .22-250 and should retail for around $20 (box of 20). Winchester also has plans to release the Varmint X in .204 Ruger and .243 Win.
