Best drop tube for 6 mm br

[Hoot]

I have found that the ID of the drop tube is just as important as he length.

I have a 10 inch drop tube with a .150 hole, it allows me to get the 30.5+ grns of 133 in my 6PPC cases and have plenty of room for the bullet.

Is that .150 where the funnel transitions to a bigger diameter tube, IE soda straw size, or is the entire tube ID .150? I may use soda straws but I have access to various metal tubing as well. Always looking toward Continuous Process Improvement.
