lt was a great day. I used a fx impact x mk2 600MMslug barrel to shoot JSB 33.9GR MK2 bullets. Speed is 956FPS
You can see my results, because my personal reasons (not good control of the firearms) caused the two bullets not to be in a normal state. If nothing happens, I believe this will be a good group.
