What is the max load for a 38 special using 158 jhp and Unique powder? My older Sierra manual (second edition)shows 6.4 grains as a max load, Alliant powder shows 4.3grns as a max load. Could this difference in charge wghts be from a change in the powder formula or is Alliant just being very conservative with their recommened max charge wghts?
I also checked an older Speer reloading manual (number 10 from around 1979). It shows a max load of 5.5 grains of Unique and it is labeled as +P. this all seems like a rather large spread of charge wghts.
I have never gone wrong staying under max as listed in the Sierra manual and it seems to me that the Alliant data is very conversative for 45 acp as well. Is it just me or does it seem that Alliant's reloading data is listing some pretty light max loads?
