FX Panthera .25 target air consumption

Hi All,

Starting down the path of tuning my panthera and had a good read of the threads here.

Took a finger in the air tune today of 128ish and 3 on the micro and it was pretty ok with Altaros 50gn at 910fps (going to drop that a bit)

One question I can’t find an answer to is what is a “good” air consumption per shot (rather than shots per fill)

I was using about 6BAR per shot today from the 300cc bottle
