Recently bought a heavy liner (600mm) and shooting hybrid 26gr. I was shooting 950ish fps on the pellet port. Turned the fx barrel 180* to slug port and velocity dropped to 850-900 fps and shooting 12” high off my zero. What are y’all pushing fps on the slug port and why am I so inconsistent? I restarted at 140 bar and worked my way to max (160 bar) I was simultaneously playing with hammer wheel to keep it proportionate
