I have been using it with 9 mm guns. I have a S&W M&P 9 and a Ruger SR9c.
With Frontier 124gr CMJ and Berry's 124gr. FMJ, I began using the loads that they published on their site and paperwork, but that did not work very well at all. In order to get the S&W M&P 9 to work and cycle properly, I have had to increase the powder load to 4.6gr. The Ruger SR9c works OK with 4.3gr, but not any lower.
I am about to change to Berry's 115gr. FMJ, and will have to start guessing all over again. I wish they had more extensive load data available.
