The Federal Barnes TSX .223 Remington 55gr load (Federal part no. P223S) is built around a 55-grain bullet and rated at 3200 fps at the muzzle. This all-copper hollow point groups tightly at long range and delivers consistent, large-diameter expansion. The monolithic design retains nearly 100 percent of its weight on impact, and the grooved shank minimizes barrel fouling while improving accuracy. Hunters who prefer a one-piece copper bullet for deep, reliable penetration will find it a straightforward fit. This Federal box holds 20 rounds, enough for a sight-in and a day afield.
