AA powders

Waschbaer · 06-07-2004, 02:16 AM

I am fairly new to reloading, and have only ever used aa nr. 5 in my 9mm and 7,63 mauser loads. However, aa nr. 7 was specifically designed for the 9mm, and I'm wondering if there is actually any benefit in switching powders at this point. Does anybody know how these two (id est aa5,7) compare to the original powder used around wwi? finally, if the original loadings stayed around 1075 fps for 9mm para, why are all the new rounds loaded around 1150+, and should one rather use the lower loads in the parabellum or does it make little difference? Thanks, Tom.
