Re: good powder for 9mm and 45acp?
Hodgdon Universal made hare called Ap70N or a seccond choice is Alliant Unique they are so close to being hte same the data will work from one to the other if not to hot. the 45acp is easy as it will work with faster powders well but the 9mm is better with a slightly slower powder as it runs at higher pressure but both will push a 9mm 125 over 1000fps and a 230gr 45 at 800fps making it the best powder to use. Universal burns a lot cleaner than Unique so it was the first choice for me as a powder for multiple calibres. i have used universal in, 9mm, 40, 10mm, 38spl, 357, 41mag, 44spl, 44mag, 45acp, 455 Webbly, 45colt that is why it is called universal as it will cycle semi autos and work with medium loads well in most revolvers. it will not be the best for hot handgun loads but gives good performance in most pistol calibres.
