Modern loads for the 454 are some what watered down.
When we loaded for the FA revolver only , some of the loadings
would go 80,000psi or higher [careful with the "old data"]
Modern 454 cases are thicker and hold less powder.
So much so that the old loads won't fit.
I have shot loads that match factory 460 [from same length barrel]
with 240-260 gr bullets in an FA454 with the old cases and loads,
but would never shoot them in other makes of guns...
