      Greetings, All!

   There was at least one Tranter / Webley No.1 .577" Revolver with an Auxiliary Powder & Ball cylinder; it was
written up in an "Guns & Ammo Annual" in the 70's...
   These Magnum Double-Action Cap & Balls look magnificent! So... Who in Italy is going to step up to the plate...?

                         M.T.M.

Dream on, McDuff.
In a world where just how much cornmeal to put in your cartridges is regularly discussed, - not nearly enough people can afford to hire the stout fellow needed to stand behind you pushing against your back when you'd go to shoot it.

How about that center barrel on the le matte? You could add powder and lead to top anything couldnt you?

Hi !
You have not been informed that this austrian revolver is a "dorn-revolver", i.e. has a "tige" in each chamber, to give at any bullet the same position, when charged.
In this way, the volume of the "tige", reduces the volume of the powder, so : EVERY evaluation of the charge must consider this constructive detail.
You must remember the short  Lorenz "Dorn-stutzen M 1854", a rifle for austrian Yaegers, with a chamber of similar construction, also arrived in the US with the CW
The name of this Dorn-revolver is M 1861 Scheinigg; was made in 13,9 mm. and 11 mm. calibers. The 13,9 mm. was the same of the Lorenz rifle, and I suppose the bullet was the same.
It was a pistol for Officers, but the the Big and the smaller 11 mm. were also used on the civilian side.
In Europe is quite rare.
Hope to be of help to clarify the matter ..
Bye, Gianfranco

Simple calculation.

562" round ball=240 grains. ( same weigth as a 44 mag standard bullet).

The chamber  measures 14 mm diameter x 27 mm long= 27x3,1416x 49 =41 cubic centimeters = 58 grains  3F powder maximum charge,

In short, 240 grain bullet X 58 grains charge.

By comparison, a Colt Walker

141 grains bulletX 55/58 grains maximum charge.


Calculations based on 240 grains/141 grains= 1,7 times more mass in the 562 round ball than in the 454 ball, so this revolver migth well almost double the Colt Walker in muzzle energy.

This revolver  is based on the Adams Beaumont design, which was vey sucessful and efective. There are several units  of them in collections and museums in Europe, so it was industrially manufactured  and relative sucessful, but not in the USA so it was virtually unknown to US gun writers, thought well documented in Europe.

Lets not forget the original british Adams Beaumont  Dragoon  revolvers, the large frame configurations, shooting a 540 " caliber bullet of 227 grainsX60  grains of powder....quite more powerful, around 60%, than  the Colt Walker,

So Myth busted, no, the Colt Walker was not the most powerful Revolver, as both British and Austrian large caliber industrial revolvers were quite more powerful.

Let me educate you since you think the Adams (1851) is more than what it was actually worth.

It typically had a .454" ball, with a muzzle velocity that only ever reached 168 m/s. The highest caliber it was ever outfitted for only reached up to .500" or 12.7 mm with both having a grain of 40. So how you got ".542" is a mystery. Even the .450 Boxer ammo used by the subsequent Adams-Beaumont only reached .455" with a power of 286 Joules and 332 Joules even with smokeless powder. It had only 13 grains of black powder.

The Colt Walker had a standard .457" ball with a muzzle velocity of around 300 m/s and had ~480 Joules of force with period powder and 680 Joules maxed out with smokeless.

(44 Walker, 1847 - 9 inch -60 grains - 3F Pyrodex - 210 gr, .458 Conical - 1014 ft/s -479 ft-lbs) - Info based

Now that goes all out the window compared to what Cap'n Redneck posted what with the custom-made revolver and it's .735" - .0750" ball plus 3F shotgun charge it probably would have the power of a pumpkin ball round for a modern shotgun. It most likely beats out everything at the period.

Also Fun Fact while I'm here. The Adam's revolver was not the first handgun to feature double action, that title belongs to Guillaume and Gilles Mariette of Belgium who created a Pepperbox with said system in the 1830s - 1840s.
