I'm not 100% sure, because there could have been some diffusion of atoms changing the crystal structure a bit. Nevertheless, the main process you'd expect to happen at 300°C would be to free up domain wall motion allowing demagnetzation, which lowers the magnetc potential energy. That process would be reversable by your remagnetization.
So my best guess is that it would be pretty close to initial specs, but assuming that the original structure was optimized, it's likely to fall a little short.
