I always refer to the manuals.
My be some of you other long time reloaders have noticed what I have. Over the years, charge weights for max loads have been dropping.
The Powder Companies say it's a change in FORMULATION leading to less powder required to reach a certain pressure/velocity. Who knows ?
But I still go by the latest book when looking/checking new loads.
