"The first thing that I would suggest is that you get some WWB 115-124gr FMJ or PMC 115-124 FMJ ammo and try that. If these Lugers function correctly on factory ammo, then your handloads are the problem. If not, then I would consider changing out some springs, etc. I am assuming that these Lugers are clean everywhere, and well lubed.
I am not familiar with that specific powder in my handloading. I do find that a medium burner works best for me and my Lugers. Do you by chance have any Unique powder? I have had good results with it, BUT, I would start with factory ammo first. If you have problems with good factory ammo, then I would look at the Lugers."
I totally agree with "rhuff", have you cleaned properly, and lubed your guns?
How is it possible that both of them have the same problem?
