I have been using Winchester small pistol primers in loading 9mm. Reloaders Bench in Mt. Juliet, TN didn't have any Win. So I bought Federal SP primers. I am using a 115 grain FMJ, with 6.0 grains of Power Pistol, and col at 1.120. Thisa the load with the Win. SP primers. The Hornady 6th Edition has the max load at 6.7 grains of PP. I have used CCI and Win. primeres with no problem. I also, picked up 1000 CCI LR primeres while I was there. Thanks, gearyr
