Dented case on ejection

[stokesrj]

Sorry, let me be more precise. The case was extracted from the chamber in all cases but was not ejected properly.

Four shots resulted in spent case remaining loosely just above magazine. This of course interfered with insertion of next cartridge (this occurred twice). I then shot with empty magazine inserted three times. Twice the result was loose cartridge sitting on top of magazine with bolt locked back. Once the case was properly ejected.

It sounds like the spring is now too short. I hope you have another and can trim it less.
