Re: [MH] Ten bore Colt 'pistol'
If you can get the stats on the bullet: bullet weight in grains, velocity at the muzzle, I can approximate the diameter of the bullet as a perfect sphere and get a decent damage value. If you know how much black powder is used in a charge, I can give it a shot at estimating muzzle velocity. I’ll see what I can dig up, if anything, via the net.

Re: [MH] Ten bore Colt 'pistol'
I am as sure as Wikipedia is... It would be interesting to see if both systems were used at one time. Pretty sure that wire and sheet for precious metals isn't gauged with Troy pounds but there are a lot of historical gauge systems.

Re: [MH] Ten bore Colt 'pistol'
This is an excerpt from THIS webpage...
"The term “dram equivalent” is a holdover from the days when shotshells were loaded with blackpowder. Blackpowder is (or at least was) measured in “drams.” This is a weight measure, where 16 drams equal one ounce. At that measurement, 256 drams of blackpowder weigh one pound. (Trivia bonus! A pound of blackpowder is actually known as an “avoirdupois pound.”) All of that’s fine and good if you’re shooting a blackpowder shotgun — and that’s not likely. The shotshells you find on your retailer’s shelves today are, of course, loaded with modern smokeless propellents. These gunpowders are much lighter than blackpowder in the same volume, thus, loading a shell with smokeless powder using a black powder weight chart would be akin to shoving a small stick of dynamite in the barrel." There being 7000 grains to a pound, a dram equals 27.34375 grains. A square load is such that the same weight of the shot is equaled by the weight of the blackpowder involved. A 10 guage shotgun fires shot equal to 1/10th of a pound, or 700 grains total. If there are 9 pellets per shotgun shell, then each pellet would weigh about 77.8 grains. I'm still trying to discover where I misplaced my Cartridges of the World reference book. Once I find it, I should be able to get more specifics on the shell itself, and then try to translate it directly to GURPS stats. Until then, I'll simply keep an eye open for the book, and ask a few friends if I lent it to them or not. :) |

Re: [MH] Ten bore Colt 'pistol'
So this thing is a revolver that shoots a ball roughly 19 mm in diameter, that weighs 700 grains and is black powder.
Black Powder has a typical chamber pressure of ~20k psi, but since this is a revolver we should expect somewhat lower, ~18k psi. The barrel length is 12" or rougly 305 mm. With all this data I'd give it a damage of 3d+1 or 3d+2 pi++ (just a reminder, the Brown Bess musket/cavalry carbine that shoots the same ball out of a much longer, 46 inch barrel, is 4d+2 pi++) with a RoF of 1 or even 1/2 considering how clunky it is to use. But definitely not 6d+3 pi++ or what the other suggestions were. A Rcl of 7 to 10, but at this point its not like it matters. A ST requirement of 12-13 (I'm leaning on 13) or even 14, weight is 6.5 lbs unloaded. Acc of 1. Reload times as standard for caplock revolvers so 30i. Range of 85/950-ish. Edit: it's 19.7 mm ball, so 3d+2 pi++ is more in my zone of confidence for this, for the Rcl values I'd pick 7 personally. Afterall this much lead is usually fired from 10+ lbs guns and not 6.5 lbs ones and even the Brown Bess has an Rcl of 4 for this. Last edited by MarcellRaba; 10-23-2019 at 02:15 PM. |

Re: [MH] Ten bore Colt 'pistol'
Yeah but you have to account for the much shorter barrel length, you will never get 6d+x out of this unless you pour like 25 drams of powder in one cylinder and apply a barrel extension.

Re: [MH] Ten bore Colt 'pistol'
Being a revolver, the cylinder pressure will not change.

Re: [MH] Ten bore Colt 'pistol'
One other advantage is the ammo is big enough that you can build the interesting custom stuff that monster hunters and such need.
