In a Saiga 410 bore shotgun and using a short Saiga 410 bore rifled choke tube Lee cast bullets of 195 & 210 grain (for the 41 magnum) were perfectly stabilized.
It had very deep rifling, about .009 to .010 on each side.
The following is the same rifled choke tube, although the longer one, that could be cut and threaded for making two screw-in rifled chokes, I suppose.
