You are assuming that changes in propellants or other components will cause a large (dangerous) change in generated pressure. If this was the case, we would have read about Hodgdon recipes and others causing a firearm to self destruct. I say Hodgdon because they never used to publish bullet manufacturers, just things like 50 gr, or 60 gr loads.

i have never seen a warning in any manual advising users to confirm the book load with a chronograph before attempting any loads in their book. I have read that reloaders should work up loads and not jump to the maximum. I do not believe that any company will publish information that is clearly dangerous or irresponsible. If you cannot trust a manual published by a major manufacturer, then I would suggest you shouldn't be reloading.
