+1 for Cort,
things change so fast, that i have changed to using the net, Hodgden, Alliant, Vit, Western, etc. as well as Nosler, Sierra,
i have the manuls going back years, also the Sierra I6 which lets me check differnt bullet mfgers, as well as run crono data through the program.
all manuals are produced over a years time and thus powder lots, primer lots, brass, bullets, are not what you buy, second the bbls are often in universal actions, and are pacnor, using the smallest chambering first and rechambering as they go up the cartridge scale in size. thus the later chambering are in bbls that have had a lot of shooting,
Bob
