Federal Premium BYOB is a bulk box of .22 WMR rimfire ammunition with 250 rounds in the package. Each cartridge carries a 50-grain jacketed hollow point bullet in a brass case, and the listed muzzle velocity is 1530 feet per second. The ballistic coefficient is listed at 0.158, and the load is made for compatible Magnum rimfire firearms.

The 250-round count suits shooters who go through rimfire ammunition quickly during regular practice, plinking or target work at the range. A bulk box means fewer trips to restock, and it is a sensible stock-up item for anyone with a compatible .22 WMR rifle or revolver who shoots often. Check your firearm's chambering before you load. The listed velocity of 1530 feet per second and the 0.158 ballistic coefficient are both on the spec sheet for anyone comparing loads.
