Welcome! Here are some tips for using this forum.
I set up a Burnham V7 with a Beckett AFG firing .85/80B,
-.02"OF, -.04"breech, good pump pressure, but couldn't get near a trace of smoke without the co2 in the high teens.
I had to open the air gate all the way and the band approx. 1/2" to get it down to 12%. A trace of smoke was at 2 on the gate with the band closed and the co2 too high.
81 1/4% efficient but I was looking to get a little more smoke in there. Any ideas would be appreciated.
Thanks and Happy New Year to all...........Dan
