Newbie, Thrown Into The Luger World By Accident - Page 4

So, there are many factors that go into producing ammunition.
The over all shape and length is just a critical as the powder used and the bullet. That's petty much how we have figured out that the Winchester White box 115 grain FMJ, which is a "target load", is idea. If they don't work, the gun is really out of tune.

A hollow point, half-jacketed or lead bullet is not likely to feed well. Stick with FMJ.

There is a main spring chart around here somewhere.(below) It has recommendations for all kinds of lugers. It sounds like you have adjusted one before - they are tricky! (not speaking from personal experience - that's something I have yet to try!)

There are springs and then there are real springs. Wire size, composition, coils, etc all make a big difference. After market springs are a gamble, so don't be afraid to swap out the extractor spring again. I'd certainly do the before adjusting the main spring. My felling is that if any rounds cycle normal, the main spring is probably set correctly.

Focus on that magazine a lot. They are very hard to eye-ball or even measure. They have to fit exactly right and not move around once they are locked into place. Lots can go wrong with a magazine. It's a critical part.

The weapon's components will obviously need to be replaced or repaired.

Sorry it has taken so long to get back here. I don't get to the range as often as I'd like. It does seem I'm on the right track. After firing last time and having the problem, I used a .30 bore brush with a little solvent in the chamber. With the amount of rust and dirt I've gotten out of this thing so far, it seemed a fair bet that there was some varnishing in the chamber. That could cause the problem. I got a chance to do some shooting today, and the jams are much less frequent. I gave it another good cleaning today. Hopefully that will bring an end to that problem and let me address the last two. Without knowing if this was going to work I've been buying parts one at a time, so to speak. The only remaining parts to be replaced are the hold open lever and the spring for it. The other problem is still that loose safety. I've got to find a way to get the pin out so I can remove, inspect, and/or replace the safety.
