In case you haven't seen one of these before.
Hi There,
Thanks for posting your pics. That original round is pretty corroded.
Was this a relic dug up from a battlefield?
Being a fan of both S&W's and Winchesters, I think that there
mutual origins is fascinating.
I have been curious about the "rocket ball" round. What happened
to the metal disk in the base of the round when the round was
fired? I would think that it would have been blown out when
fired. So, did it remain in the barrel? It would have been smaller
than the bore so it wouldn't present much of an obstruction.
Did they figure that the next round would just push it out?
Also, how did one eject a live round? I see nothing that an
extractor could grab to pull it out of the chamber. Just curious.
Cheers,
Webb
Another major problem with the early volcanic design is the rocket ball conical bullet would reside up against the live primer of the next live round in the tubular magazine. Which could ignite the rounds in a chain fire and cause an explosion in the magazine. It's documented as actually occurring during period of use. That's why they went to the flat nose bullet in the Henry and 66' Winchester tubular magazine rifles. I'm not sure if the rocket ball ever saw a flat nose bullet to eliminate that problem?

An interesting video from Rock Island Auctions with lots of details about Volcanic No.2 ammunition for those interested. The box below was sold for $43,000 in 2020.

These look nearly as "rough" as mine does. I guess that's normal over time and suggests mine was not a battlefield find as "dug up"?
By no stretch of the imagination is the .41 Volcanic a powerhouse. From what little I have found, it carried a 6.5 grain BP charge, with a projectile MV of around 250 ft/sec. it has been compared ballistically to the .41 RF Derringer. That may not be a fair comparison due to the very short barrel length of the Derringer.The one issue that has always been lacking is accurate research on the 41 caliber during the early black powder era. Both the early Volcanic and the 41 derringer rounds. They were not barn burners by todays standards but they were also not anemic. Modern evaluations are often poorly researched.
The problem with the 41 rocket ball was not the lesser powder charge. It was the poor early ignition design accompanied by an extremely short viable lifespan. In other words, they poorly ignited the main charge to begin with and became duds very quickly due to the early design and ignition material used failing in short order.
I've been reading a lot lately about the viable lifespan of early copper cased black powder cartridges. According to the Chief of Army ordnance records, significant corrosion occurs in less than 2 years! That's why they went to brass cases. I would speculate that the early 41 Rocket Ball ammo was good for less than 1 year! After which it would miss-fire or not go off at all.
If one was to manufacture new, viable ammo using a matching powder of say Swiss black powder in FFFFG and attached a fresh hot reliable primer with the correct sized and lubed bullet? You might be surprised at the actual original performance of the "Rocket Ball 41"! Shot from an 8" barrel repeater? I wouldn't want to be in front of it.
