loading 9mm with 4.5gr redDot, and a 125gr RNLead bullet. In my S&W 559, it fires, but doesnt always load. I thought that at 4.1 red dot, it wasnt powerful enuf to cycle the slide. It ejected fine. so I went up to 4.5. same problem. It ejects the casing, but stays locked back. So I have to manually have to rack the slide. this happens about every other shell. With factory(UMC) rounds, the gun functions perfectly. I have a OAL of 1.105, verses the factory OAL of 1.103. And my OD of the case is .376, factory is .377, so I am close with all dimensions. Any thought??
