Its been years since I have re-loaded .357 Mag. pistol ammo. and I want to blow the cobwebs out of my Tarsus.
In the past I loaded my .357 Mag. with Acc.#9 powder and data was obtained from Speer Manual 1995 + Hornady Manual 1997.
The newer manuals don't list Acc.#9. Am I still safe to use the data from my older manuals or play it safe and use another powder?
Powder want go to waste because my M1 carbine still uses #9 in all the up to date manuals.

Thanks for any help

You older data is still valid. If you want newer data look at western powder web site for gods of data with aa9

Here is the pdf file of Accurate's reloading data. Plenty of #9 loads for .357 mag.
