Conversion Question, 1858 NMA

Post by Choctaw Dan »

I'm a writer, in the early stages of crafting a novel that takes place in northeastern New Mexico in the early- to mid-1870's. Here is my question:

Would it have been feasible for a skilled gunsmith of the era to convert an 1858 Remington New Model Army revolver to .44 Colt (not .45 Colt -- it came too late for the story line)? I've reviewed the dimensions of the .44 Colt round and it seems doable, but I'm by no means an expert. Help?

As I recall the 44 Colt started life in 1871 and the 44 Rem in 1875. The Colt lasted until about 1940 while the Rem only until 1890. Both were heeled bullets with similar characteristics. I believe either would work in a NMA.

Yup, the .44 Colt came out in 1871. Thanks!

In another thread on another topic, someone suggested the .44 Smith & Wesson American cartridge, aka .44 American, might be a worthwhile round to consider. It was introduced in 1869, so it would be 'established' in my timeline. The bullet diameter is a little small, but the bullet was heeled.

So, whadda y'all think?

As long as it's for a novel I don't think it really matters. A good smith could chamber and time a NMA for any of the rounds mentioned. Also, have you ruled out rimfire rounds available during this time period?

It really matters, considering the likely readership.

I have considered the rimfire rounds, and am still doing so. As Yogi Berra once said, "It ain't over 'til it's over."
