All pressures and velocities are within SAAMI specs. I have tried new brass, once fired brass and range brass and get the same issues with either a failure to fire( which is more of a failure to go into battery), failure to extract or feed. Get an occasional light primer strike. A few rounds will fire then I get a failure for a few round. I have taken these same loads and ran them through my S&W pro and Glock with no issues. Just these two 1911’s
