Default Choke Constriction

Boxbirder; With respect to your choke constriction , see several of my PP and DGJ articles about the Super Fox and several Parker competition guns. Choke tapers, measured with a Stan Baker and a jig are shown.
Parker chokes were reamed and polished "to deliver" on the customer's request. Some look pretty bad but deliver tight patterns. It is not necessarily the actual diameter, but the rates of changes in diameter that make patterns.
I would not re cut that choke before counting at least 10 patterns on two days.

Best, Austin
