That is a discontinued bullet. Sure it is safe with the right data. Hornady manual 9th edition page 218 still listed the data for them. Them bullets were designed for 6mmTCU type speeds. They will detonate in an animal at normal uper end .243 speeds. So do not shoot anything with them you intend to eat, they will be essentially varmint grenades at 243 speeds. The right person might make you a swap for more robust 243 bullets. Those guys that still shoot a 6mmTCU in a contender would appreciate them for sure.
