Just an FYI Guys, with all this talk about shooting shot from pistols, et all, I was a wonderin myself how the standard Shotgun Gauge sizes compared to Caliber diameters. I came across this little nifty chart...
I also noticed, that some of the caliber equivalents worked out to close to some of the standard sizes for mini-ball mold diameters. Although no-one has brought it up, I think that if people can shoot solid lead plugs out of standard shotguns, there should be no reason why a muzzle-loader couldn't fire out a properly sized mini-ball, of course, with no rifling in the barrel, they would not be as accurate as a mini-ball fired out of a rilfed barrel, but, for short shots, they would be accurate enough I think.
Gauge Milimeters Caliber
-----------------------------
06..... 23.3......... 0.92
10..... 19.7......... 0.77
12..... 18.5......... 0.73
14..... 17.6......... 0.69
16..... 16.8......... 0.66
20..... 15.6......... 0.615
24..... 14.7......... 0.58
28..... 14.0......... 0.55
32..... 13.4......... 0.526
I noticed two things about the chart, they left off the bore diameters for the gauges that are reffered to by diameter, and not by Gauge, such as the 410 Gauge size, which is a diameter of .410. The chart also does not include the 8 Gauge size, If anyone has that information, that would be helpful to completing the chart.
I learned a couple of interesting things from the chart, for one, the 20 Guage size comes out at .615, which means that its the perfect size for a patched 61 Caliber round ball, and that the 14 Gauge size works out to exactly .690, 69 Caliber, so you would need a sllightly undersized patched ball for that one, perhaps a .680 or thereabouts.
And, since we have the standard gauge sizes compared to caliber, in some of the calibers I think that the standard shotgun solid lead cylindrical wads would work out nicely, as well as, some of the properly diameter sized BP mini-ball molds. But, I would, when shooting those, use cardoard and cork shotgun wads over the charge and under the lead.
I hope you all find this helpfull.
