Barrel Wall Thickness Readings
 

While following the GH 16 Damascus wall thickness thread I'm curious what kind of wall thickness readings you normally see on O frame 16 ga factory barrels.

If you own or have measured any what have you found the thickness to be ?

Thanks, Karl

I have 5 or 6 Parker 16’s on the 0-frame, some hammer guns and some hammerless. I have a wall thickness gauge but it is undependable IMO so I won’t use it and post any readings.

Dean, would you let us know what brand of unreliable wall thickness gauge you are using?

86,7XX, Damascus, 28" DH,0 frame. .028" MWT Both Bbls.
76,5XX, Damascus, 30" Gr. 2 TL, 0 frame. .026" MWT L, .025"MWT R.
59,XXX, Damascus, 28" Gr.2 TL, 0 frame. .025" MWT Both
Eric, Harold, and Allan can comment of the 26" guns they got from me.
If you want 0 Frame, steel barrel MWT, that's gonna take me a while

Bill, it is a Brownell’s. In my experience there is too much flex in the rods.

What is the proper recommended way to use it? I have never had luck with consistent readings.

I never had a problem with a Hosford but I don’t own one. My experience with a Hosford has been with the one formerly at the James D. Julia Auction House.

I 100% agree with Dean, the gauge from Brownell's is impossible for me to get accurate and repeatable measurements. The rods flex from the slightest pressure in any direction. I use the Galazan wall thickness gauge very heavy and not too portable but accurate and easy to use. Craig

Edgar,

I'm starting to look for a steel barreled 16 O frame and am hoping to get an idea of what to expect as being normal and acceptable .

P.S ... Do you happen to have any recent pictures of Percival for my wife ?

Thanks, Karl

I thought it was just me, but I've had the same experience with the Brownell's gauge. Hard to get the same reading twice.

Personally I would be interested to know what some of these O frame 16 guns measure at the juncture of the chamber and the forcing cone. My apologies to you Karl for my intrusion upon your thread but hopefully you will find this to be useful information to you as well.

That is the most critical area to measure on any classic old sxs. That is the area I would have reported if I had a reliable wall thickness gauge.
