Default 1.57” Armstrong Rifle

Gun is about 6’4” long. Breech up to reinforce ring is stainless steel. Ring is shrunk-on,chrome-moly steel. This is a friend’s project, he has fired it a few times off sandbags while thinking about a carriage. Think mold was made by Kevin Johnson quite some time back.

I am somewhat confused how it loads and works also. Looks like a great project though.


Moose, have not seen you around for awhile it seems. I did make a small scale Breech loading model of my full scale Hughes Gun, I put it up a few posts down.

Bagged charges used. After projectile and bag are in chamber, drop breechblock in place thru top of gun and rotate breech locking handle about 1/2 turn to force breechblock against chamber. Vent is in top rear of breechblock, bored diagonally downward to the front. Ignite at vent however you prefer. Vent exit can be seen as bright spot in left center of this photo of breech block.

Breech locking screw was removed for photography only, during use the screw handle is only rotated about 1/2 turn to force breechblock against chamber for firing, or to release it for loading. This is exactly how the original Armstrong breechloaders of the 1860’s worked.

Thanks cannonmn , do you know if powder bag is loose or is a preformed aluminum case used ? Reason for question is how is head space dealt with.

Carbineone1964 I have been out sick since May so activity is limited. Starting to get out more now.

Sorry about the bother but I'm not asking the right question . Normally you don't want any air space when chamber is loaded , with loose powder in a baggy it would be hard to load it flush with the chamber end so the breech piece could be installed with out tearing the powder bag . Is your friend doing anything special to fix this problem , or just seating the charge with a rammer after the breech is closed? Thanks

Very interesting project.

Sry I don’t know, I really don’t think he’s gotten to that level of detail yet, and I wasn’t there when he test-fired it.
