I have been shooting the federal flight controls out of my 835 with a ported choke tube, but ive heard recently that if you use this shell with a ported tube you defeat the whole purpose. I guess the ported tube slows down the wadding and the flight control is suppose to stay with the shot. Anyone know anything about this. To be honest my gun patterend the best with them even with the ported tube, just wondering if it would be better if it were not ported.
