Started reloading August 1971, and with the exception of 22LR reloaded everything I've shot since then. Manuals from 1956 to 2010. But now I only use Quickload as I can give it specifics (the usuals plus individual case capacity, temperature, bullet seating depth, barrel length) and found it agrees usually within 5-30 fps of my chrono readings. I do enjoy reading the books, but when I get down to actual reloading that is what I now use as a "go to". T.
