I recently started reloading for my Ruger SR9 using Winchester SP primers, Starline brass, 5.5 grains of Power Pistol and Hornady 124 grain XTP bullets seated to a depth of 1.124" I've used Winchester 124 gr. FMJ bullets in it without any problem and have never had a jam. The first magazine of my reloads fed without incident, but after that they began jamming up as the spent shells were being extracted, not every time, but often enough to cause concern as I want to use that load for home defense if I ever need to. Has anyone else had that problem? Any suggestions on what I should do? Thanks in advance for responding to my questions.
