Does anyone have a list of bore gauges larger than 1 bore?

Sure do.

They are called "Field guns".

I have seen 0ga Punt gun brass. I would not want to be in the punt boat when it went off.

I always thought that "gauge" derived from the number of round lead balls of a given size it took to equal one pound.

Thus, it would take 12 balls of 12 gauge to equal a pound, 8 balls of 8 gauge, etc.

A 1 gauge size lead ball would weigh one pound.

I think a zero-gauge is therefore impossible?????

I have heard of something called the Gun Barrel Proof Act of 18xx.....I can't find a copy of the entire document, but apparently it lists gauges larger than 0 gauge for use in punt guns. I believe they use letter designations instead of numbers. Is anyone familiar with "letter gauges"?

A gauge = 2" Bore

Proof Act of 1868 was English - Find a copy of the "Book" in a library.

Gun Barrel Proof Act of 1886 lists bores A(2.000")to F(1.668"),then 1 bore(1.669")H(1.625") to M(1.375").next was2 bore,O(1.313")& P(1.250"). after P was 3 to 50 bore.This was in force until the GBPA of 1904."A" bore proof was 18 oz.powder!
