Choked bores and tapered bores

by B.B. Pelletier

This subject came up as the result of a comment I made about choked and tapered bores. It turns out that gun makers were having this same discussion 140 years ago with pretty much the same results.

The best gun makers of the 1860-1910 timeframe (and Harry Pope for just a little longer) all either taper-bored their barrels or choke-bored them. I will describe each of these conditions in a moment. There really isn’t much difference between choke-boring and taper-boring, but the slight difference that does exist allows us to talk about each of them as a separate issue.

Most gun makers (or barrel-makers, because in many cases — like Pope, a man did not make the entire gun) did taper-bore their barrels. But that wasn’t what they called it, so the fact that they did it got lost because of the subtleties of the language. read more
