Parker GH 16 Damascus-wall thickness

[Garhart Stephenson]

That's similar to what Drew has told me his e-mail. The chamber thickness listed in your letter really raised my eyebrows! I am sorting through low pressure loading data today to find if there are any 3/4 oz. and 7/8 oz. loads that I would actually hunt with. With such light loads and the choking of this gun, it will definitely be good in the woods, but quite limited on the prairies. It's not my only gun though and I can live with it being a blue and ruffed grouse special.

Thanks for posting that Dean.
Unfortunately we can't inquire exactly where "junction of chamber & forcing cone" WT was measured.
If that is the "end of the chamber" (toward the muzzle; not breech) .068" is well below CIPs recommendations of .075" for a 20g with “Standard Steel” (Non-alloy AISI 1045) with tensile strength = 101,526-123,137 psi

Crolle damascus tensile strength averages about 55,000 psi or 1/2 that

Austin Hogan observed that factory small frame Parker 20g and 16g gun may have an end of the chamber WT < .090"

.068" is also well below any measurement documented here

It might be very interesting, and prudent, to repeat the "end of the chamber" WT measurements.
