Tom, Thanks for the update. It sounds like you are making progress. I am looking forward to installing the shroud rings and polishing the bbl. Will be interested in your testing and if the flyer issue has improved. I have a pesting issue to deal with before mine can worked on. What did you use to ream the inside of the bbl shroud rings. I am thinking a wooden dowel and sand paper. I received 5 shroud rings, and I think you only mentioned that you install 4. Wondering if you only received 4 or left 1 out for some reason.Thanks Tim
Another thing to look into if using the mag. is it damaging some of the pellets when cycling.
