Winchester Varmint X Features The polymer tip on this 55 grain bullet is designed to initiate rapid violent expansion the instant it contacts a varmint or predator producing the dramatic terminal effect hunters want when the goal is quick humane kills rather than deep penetration. At 3240 fps and 1282 ft-lbs of muzzle energy this load carries enough velocity to flatten trajectories at typical varmint hunting ranges making follow-up shots easier when working a field full of prairie dogs. The sleek bullet profile also helps the round buck wind better than a blunter design which matters when shooting at small targets across open country. Winchester built the Varmint X line specifically around the needs of predator and varmint hunters distinct from their standard big game hunting loads which means the bullet s expansion characteristics are tuned for smaller thinner-skinned animals rather than deep-penetrating deer loads. Brass casing keeps the load consistent from round to round and gives reloaders reusable cases after firing. Coyote hunters and varmint control shooters looking for a dependable .223 Rem load built specifically for their application will find this a strong match for that role.
