Underwood Ammo Ballistic Tip Varmint Features The Underwood Ammo Ballistic Tip Varmint in .223 Rem is built around a 55 grain polymer tipped bullet designed specifically for violent expansion on impact. The polymer tip is driven rearward into the bullet s nose on contact forcing the thin jacket to peel back and fragment rapidly rather than punching a narrow wound channel. That fragmentation is exactly what varmint and predator hunters want since it maximizes tissue disruption on thin-skinned animals without over-penetrating. Loaded to 3300 fps and delivering 1330 ft-lbs of energy at the muzzle this round carries enough speed to make the bullet s design work as intended at typical field ranges. The boat-tail profile behind that fragmenting jacket improves the bullet s ballistic efficiency helping it retain velocity and resist wind drift better than a flat-base design of the same weight. A reinforced heavy base backs up the front-end fragmentation by resisting deformation during the violent acceleration of firing keeping the bullet s flight consistent shot to shot. Each round is built on a reloadable brass case with a Boxer primer giving handloaders the option to recover and reload spent brass after a day at the range or in the field. Packed 20 rounds to a box this Underwood Ammo Ballistic Tip Varmint load is available for sale at GrabAGun for varmint hunters and predator callers who need fast explosive terminal performance in a dependable .223 Rem package.
