Almost every Sauer I have seen is choked full and fuller.

I had a WW Greener waterfowl gun with good stout bbls that bulged at the choke with lead shot. After the fact, we found out it had 60 thou of constriction. The gunsmith who repaired it said it's not uncommon for tightly choked older guns to bulge with lead shot.

Best bet is to have the chokes opened up a bit...nobody needs anything more than 40 thou. You can't hit anything and if you do it disintegrates.
