An economical vernier caliper capable of making accurate measurements to 0.001 of an inch [0.0254 mm] wasn't invented until 1851 when it was introduced by Joseph R. Brown [Brown and Sharpe] of Providence, RI. It was not until 1867 that Brown perfected the micrometer caliper. These are two of the most basic modern machinist’s measuring tools. So, you are correct that simply measuring things prior to and during the Civil War was a problem. But, you can't have weapons in which your bore is smaller than the bullets in your ammunition. The ordnance establishments in armies around the world issued their inspectors "go/no go" gauges to ensure that bores were neither smaller than their established ordnance standard nor larger. Anything that didn't meet standard was supposed to be rejected and condemned. Similarly, gauges for bullets and finished cartridges [where the bullet was loaded in the greased paper wrapper] were issued to the ammunition laboratories.

Re Burnside caliber, caliber designations are sometimes terms of art: the .38 Special, .357 magnum, 9mm, and .380 calibers all essentially measure .357 inches. What matters is true bore diameter and sizing the bullets to that.

380 and 9mm are actually .355, but I know what you mean.

That Model 1841 is one of the most beautiful US martial arms ever made with a lot of history going for it. And you have one that appears to be in exceptional condition as well as being produced in Harpers Ferry. Thanks for sharing the photos.

The new July-August issue of True West Magazine has a two-page article on the 1841 Mississippi Rifle by Phil Spangenberger. Very interesting.

Thanks bayouace,

I'll look for it. I remember reading a review of the Mississippi rifle back in the '80s by of all people, Phil Spangenberger. It was an Antonio Zoli replica that he was firing with a patched round ball and he did quite well with it. Glad to hear that he is still publishing.

He usually has at least one article a month on firearms in True West.
