Anyone here have any knowledge of chokes such as these, thoughts ? There are no surviving records on this one BTW.

I spoke to a friend yesterday who has done extensive pattern and ballistic testing with all kinds of loads and choke constrictions, including going North of 50k constriction. (He has tested up to 55k all in a 12 ga.)
He says that in his experience 50 k is where patterns start going the other way with shot cup ammo. (note clever avoidance of "modern")
Patterns were good and even with the ultra tight chokes, but measured larger diameter patterns.
He speculated that with vintage type shells the 60 some thousands chokes might throw pretty good and of course tight patterns.
Gonna have to put this one on paper and see what it does.
