Does anyone have a list of all of the gauge sizes with their corresponding diameters in inches? I am looking for a complete list all the way up to the "punt gun" gauges.

Thanks

I can help get started.....you do the math based on data from this thread

there are (at least) the following gauges based on my shell collection

8 Ga
10 Ga
12 Ga
14 Ga
16 Ga
20 Ga
24 Ga
28 Ga
32 Ga
410 bore

possibly more but these I have samples of

there might be 18 Ga out there somewhere as well as others.

I think he's looking for the actual bore diameters of the various gauges, which is available in a number of reference books (that I don't have at my disposal at the moment).

However, I'll add the 4 gauge, which was used, of all things, for cleaning slag from the interior of kilns. And the 9mm shotshell, a delightful little target gun.

I pulled this form a referance chart I had handy

Gauge Bore dia.
4 .935 to .955
6 .919
8 .837
10 .777
12 .729
13 .711
14 .693
16 .663
20 .617
24 .578
28 .549
32 ? not listed in my chart
.410 is about .45 bore dia. , because there are .410 / 45 colt handguns

This chart I pulled off the net

Gauge Bore Diameter
1 1.669"
2 1.325"
3 1.157"
4 1.052"
5 .976"
6 .919"
7 .873"
8 .835"
9 .802"
10 .775"
11 .751"
12 .729"
13 .700"
14 .693"
15 .677"
16 .662"
17 .650"
18 .637"
19 .626"
20 .615"
21 .605"
22 .596"
23 .587"
24 .579"
25 .571"
26 .563"
27 .556"
28 .550"
29 .543"
30 .537"
31 .531"
32 .526"
.410 .410"

I have a referance for a true 36 gau .
But no dia is listed

Thanks for that. These lists are exactly what I am looking for. Has anyone heard of gauge listings bigger than 1 or 0. I found an article on the net about a punt gun that was "A" gauge. It also referred to something like the "barrel proof act of 1886".....???

I've heard of an "A" gauge. I believe it was a Dutch designation, but I could be wrong. I'm having to jog many years of memory. As to the exact size, I can not recall, but it was listed in the back of a Dixie Gun Works catalog for information.

Just to add to the mix,
The 20 Wingo shotgun, 582ga
There are 22cal smoothbore shotguns,
6mm shotguns, 353ga (in 3 different lengths, single double and triple charges)
7mm shotguns, 223ga
The 310 Rem shotgun
The 9mm shotgun, 105ga, has already been mentioned (in 3 different lengths, single double and triple charges)
The .410 would be a 68ga BTW
