Best powder for 9mm
I have the Beretta 92 and Golck 26. I have used data in Hornady#fouth edition. I have used the 115 grain and the load data using Olin 231 for the 115 is 4.5 starting and 5.5 max with sp primer. The 124 for 231 is 4.7 starting and 5.3 max. I have shot the 115 grain load using a mixture of brass for years and untold thousands of rounds. Olin 231 is an excellent powder.
