I don't know if it will help your exact situation, but I put new coulters on my redball units last year, I found that I could get a 22" diameter to fit without modifications. This fall was having trouble not moving enough dirt, ended up I was slicing too deep, and the slot opened up around the shank so it wasn't pulling up as much as it should. I ended up shallowing the gauge wheels and dropping the shank down 1 hole. That seemed to help. I've never had issues quite like you describe up front, unless in really loose dirt for some odd reason (going over a previous pass or something disked like a fence line. I am running in the middle position on my coulters, and just one hole mostly visible of the shank sticking above the mounting bracket.

Where I have issues is due to old age/ wear - and issues with the row cleaners not moving the residue enough, plugging with the row cleaner, then building from there. I had cover crop drilled this fall, and had the best fall conditions afterwards that I've built fall strips in. I am getting to the point where there is row unit wear that I can't take out with new bushings, so at times the row units want to run tipped to one side or the other, dropping the shank a bit deeper has helped that situation by pulling the row in and vertical at the same time.
