I like my Nosler manual but it doesn’t seem as complete as my Lee, more powders and bullet weights shown for each cartridge. But there’s differences between the powder charges listed in many cases. Like others said, you kinda have to find your own sweet spot and max load. On top of that, I would mention that even inconsistencies with yourself can be overlooked sometimes. My Model 7 308 likes 150gr Hornady Interlocks with 46gr of Varget, but it shoots the same POI with used Federal Brass, used Hornady Match Brass and brand new Hornady Brass. I can’t say that works for everyone, but it hasn’t given me any issues with that particular gun.
