I liked the Nosler manual so much, I went out and purchased their book. Use both. At the time, I was really impressed. However, now as most of my loads are for PRS rifles and not hunting rifles nor IHMSA handguns, I refer to the online Hodgedon manual more than any other. It has so many rounds that the traditional books can’t keep up with.
Still, I always recommend having at least two, preferably three book manuals hanging around. The instructions to new reloaders are invaluable, and despite the best efforts, not every recommended load works in every firearm.
Examples found in a 40 something years of loading….Starting loads for the .223 handgun section in a popular manual nearly locked up my beloved little Kimber of Oregon Predator. It was a hot day). Further, one book recommended a load of 45 grains of H4350 for the 6.5 Creedmoor and a 130 grain bullet. Every other book recommended a max load of about 43 grains. It happens.
Caveat…IHMSA handguns are pretty much of a crapshoot, try to find something that works and be careful was always the plan of the day. Even when we shot factory rounds, they were always load quite differently than traditional loads (such as 80 grain Berger VLD’s in a .221 Fireball, or using SR4759 in the 7 Bench Rest) Mostly we shot unpublished wildcats.
