Default DHE Barrels

0.696 inches is the "nominal" full choke diameter of Parker barrels after s/n 70000 - see Dave Suponski's article on this in Parker Pages a few issues back. A contoured reamer was used to bore and form choke in one pass; a nut borer was used to adjst the choke if necessary to meet the customer's request. 0.715 is a little larger than later modified choke, but we have few modified choke measurements on guns less than 200000 s/n to compare.

Best, Austin
