S/42 fire test, jammed b'z of 115 ammo

M:
Regarding your very last question, the round may not be hitting the ejector hard enough to be thrown out to the side, thus gets pushed forward again, jamming the works.
FTEject, failure to eject
chipped claw probably refers to a broken claw on the extractor, but that's just a guess.
You have gotten good advice. Good known ammo. One round then several, however resist jamming the magazine completely full. Load 5 or 6.
If you replace the magazine, go with Mec-Gar brand.
If you can photo the "hook" on the back end of the ejector spring (strip of metal on the right side) it may help us.
Above all, be patient, don't go brutal or medieval on the gun. We'll get you thru this hic-up.
