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.

The subject gun actually arrived Thursday afternoon. I have had a chance to do a full evaluation and measuring of this gun. As it turns out the dealer with 40 years of experience does not know how to measure barrels. That really did not surprise me one bit as I did not fully expect this gun to be choked as was indicated. I hope that I have time in the next day or two to add another post to this thread and which I intend to show what the dealer indicated the gun to be versus reality. I think you will find it interesting. At the end of the day I'd previously handled this gun and I'm still thrilled with it. It is a beast, even if it doesn't have 60 thou constrictions.
