I try to keep the latest version of paper manuals on hand, but if you want the latest and greatest information, the only place to get it is online. For some cartridges like the 6.8 Western, older or wildcat loads, that is about the only place you will find it.I've been loading for over half a century and have several manuals on hand plus the internet but there are so many more new powders out there, particularly IMR powders.
What manual would you suggest that includes the new powders with an array of bullet manufacturers.
