I took this pistol to the range with the following results...

Winchester 115gr white box ammunition. It's all I had in my safe - usually feed to one of my H&K's.

1. First (and any manually chambered round always fired flawlessly.
2. Second round chamberd about 50% of the time and fired fine.
3. Second round failed to chamber about 40% of the time.
4. Second round jammed about 10% of the time with case showing that the bolt captured the round at the casing's groove.
5. Extraction and ejection worked fine for 48 out of 50 rounds. Two rounds extracted but failed to eject leaving the spent cartrige vertical, caught between the bolt and the breech.
6. The bolt failed to lock back after the last cartrige every time.

Thanks to a little fingernail polish supplied by a woman next to me at the range, I was able to determine that the bolt was not being driven far enough back to insure properation.

I need a different main spring or more energy imparted to the bolt from the round.

When the become available, I'l try a heavier round.
