I genuinely appreciate both of your replies. Sincerely. That's the only area that concerns me.

I do have a lathe, and can give a aggressive cut at the mouth. Or reprofile the choke itself if needed.

Mag410, is there any way you can measure the reamer OD at the transition?

And if you don't mind, the inside diameter of the bushing
