Ernest I’m not sure how this plenum tube operates but it is interesting that you are getting such a large increase in velocity. Is it just a larger reservoir of air we are talking about?
Mine gets 860 fps maxed with 34gn Heavies. Other guys are getting much higher. like 880-895 I’m thinking that my probe is not lined up properly with the air transfer port.
