After discussing choke measuring with brother Dave I remeasured all the unaltered chokes I have on hand to find the elusive parallel section at the end of the ogee. This is what I found:
(10) Damascus barreled 10 gauges NONE had a parallel section.
(1) Parker Steel 10 gauge PHE made in 1925 HAS a parallel section.
(3) 12 Gauge to include (1) Titanic Steel HAVE a parallel section.
(3) 12 Gauge all Damascus DO NOT have a parallel section.
(1) 20 Gauge Damascus DOES NOT have a parallel section.
I hope to see the spreadsheets of data on the chokes. It will be interesting since my small sample set listed above in NOT statistically significant.
