Well here it is, my ZB37 semi in 8mm. Took it to the private range today as the temperature was finally above freezing. It ran extremely smooth, even smoother than my 1919A4 Browning. Ate through a 100 round belt of Romanian ammo without a hiccup and grouped all the rounds very tightly. The credit for this one goes to Tony and Gordie K. at Wiselite Arms, great job guys. I will try and post some video of it firing tomorrow, need to eat dinner and clean the guns now.
