hi. Iâ??m back with an update.
I had tested with 124 Gr yesterday. After the last round of first mag the breechblock kept open (So I say: Thatâ?? is!) But on the next 3 mags the issue came back with an additional problem: Jamming
So as I have read that 124Gr. Is very common used by the members of the forum I will give a try with a new magazine.
