I just got a 300 Rem Ult Mag and need reloading data for the caliber. My friend got a new manual recently and it still wasn't recent enough to have 300 RUM. Anyone know of an affordable manual that will have this data? It would be nice to get smaller books for each caliber. I've seen them, but not sure if they're in this caliber. I plan to load everything from 110gr to 220, or higher if it exists.
