How 'bout this idea? My buddy has an Extrude-Hone machine in his shop. He uses it to deburr the inside of his choke tubes he manufactures. If it's not too much trouble to make a fixture to hold the rammer tube off the MEC, I may ask him to polish the inside of it with that. It'll only take a minute or two. Making the fixture may be the killer, though.

He may not see the importance as much as I do. laugh

It just might make a significant difference in the bridging problem.
