Having never used an Ejection baffle, is it practical to use a baffle in the BT-50 tube, .095 inch I.D. or are the baffles designed more for the larger tubes? Are the sizes in millimeters, as I have seen described as a Series 13, 14, 19 etc. The BT-60 has an inside diameter of 40.52 mm or 1.595 inches 1.6 inches.. What baffles would I order for the BT-50 or the BT-60 tubes, if I decide to use the baffles in the construction of the future models.
