Anyone have data on Volcanic ammo?

[LCJr]

Looking for a reference with solid numbers on the Volcanic ammunition.  Specifically bullet weight and if the weight is for the loaded cartridge or only the actual projectile portion.  Also powder charge by caliber.  Velocity figures by caliber and barrel length would be nice too.

All I found was that it has an extremely poor velocity of 500 fps according to this book.

Thanks, I've found some bits and pieces.  One reference to a charge of 6.5 grains black powder that doesn't state the caliber.  Another to the round producing 56 ft/lbs energy. Again without important specifics like the caliber and barrel length.

this says the barrel length's & the two calibur's used http://www.winchestercollector.org/guns/volcanic.shtml
how come you want this stuff?, just curious.

Same reason as always Pinky.  To try and take over the world.  Seriously? For the same reason you asked your question, curiosity.  Pretty much anything on the history of firearms makes a brief mention of the Volcanic system. The author points out its flaws says something about it being underpowered and then it's on to the Henry and Winchester.  But I've never have seen any actual specs in any meaningful context.  I'd really like to see something along these lines  "A caliber bullet of B grains weight fired from a C inch barrel produced a velocity of approx. D fps"

heres a comparison of the 56ft/lbs volcanic ammo to modern ammo for reference...
#1 the .17 HM2 round has 166 ft. lbs from the muzzle of a 24" barrel,
#15 the .30-06 round is rated at 2820 ft. lbs, I assume from the same length barrel.

edit: im starting to wonder about the accuracy of the 56 ft/lbs statement, seems like the bullet just falls out of the barrel.

My god, that's pitiful.

Using the few images of Volcanic ammunition and Hunt Rocket Balls floating around the net, one could guesstimate that the powder charge would be around 1/10 to 1/5 and the projectile weight around 1/2 of a metallic rifle cartridge of the same caliber.
Surely you gun-nuts can work from there 

And an exact figure like 56ft./lbs seems to indicate that someone has been really measuring it, not only estimating. Comparing with a list of present day pistols (http://www.chuckhawks.com/handgun_power_chart.htm), the value fits well into the lower end of the energy spectrum. So it's at least plausible for a volcanic pistol.

glad ya found what ya were lookin' for

.25 Auto is around 63 ft/lbs at the muzzle.  The S&W Model 1 was only 16 or 32 ft/lbs depending on if you believe the 500 or 700 fps figures.

If you were willing to make a major assumption that the 56 ft/lbs and 500 fps were from the same weapon that would give a bullet weight of 100 grains.
