Do you have an interesting gun? Something due to age, rarity, caliber, a war souvenir or whatever? How about a description or photo?

A miniature of this was also made; (50cal) was made in bronze for me; black powder of course is used FFg. I find that blasting powder works fine for the large cannon; the grains are about the size of a fingernail. Blasting powder is black powder but using Sodium Nitrate in the mix (not potassium nitrate); the stuff is highly glazed with graphite and has to be stored in moisture proof containers. 250g of the powder will send the projectile a good distance. Strangely enough while the country has strict fire arm controls, there is nothing about cannons.

Oh my, but that is lovely. What is the bore diameter and it's dimensions? Is the carriage original? My small collection of small arms goes back no more than 140 years so I'm totally impressed.
Some years ago had an acquaintance who owned a muzzle loading cannon but it was homemade and not nearly as handsome and finished looking as yours. His fired a quart oil can filled with concrete and about the same powder charge. Fun to shoot but had never been fired in anger. No history to it at all.
At any rate, congratulations on your piece.

Hi in your measurements it is 2.37 inches, slightly more than than the calibre of the smooth shot. 6.02cm for a 5.3 cm shot of pure iron. Lets work this out. 2 lb = 907.2 g density of iron = 7.9 gcm -3 volume = 907.2g/7.87gcm -3 = 114.9 cm 3
using the equation for volume of sphere the radius can be calculated as so: r = cubed root of 3(114.9)/12.6 = cube root 27.4 = 3.01cm diameter shot = 6.02 cm Not much room for wadding to be wrapped around the ball like a black powdered rifle before it is rammed down the bore. Gun is pretty accurate at 10m

That seriously outclasses my only 10 meter gun, a 1882 Remington 10 gauge with a 3 inch chamber and 18 inch barrels. It's claimed to have once belonged to Doc Holiday but, alas, I have no serious provenance of that. It's a grade 4 with the barrels cut down to 18 inches and a gold front bead. It's in storage but here are some photos of a 1882. www.remingtonsociety.org/remington-model-1882-shotguns/ It's almost identical to Wyatt Earp's 1882 which recently sold for $64,500.00 which is a real incentive for me to dig further into the history of the gun. As it sits, it might bring a few hundred bucks which is OK since I paid $15.00 for it some six decades ago. Facing off against your 2 pounder loaded with grapeshot at 30 meters would be a hopeless but valiant endeavor. Doing so should appeal to the British proclivity for brave but hopeless defenses.

Ha ha ha yea a cannon with wadding and the equivalent mass of 50 cal lead balls. A single ball is 11.43g, so 907.2/11.4 = 79 balls. What a shot gun.

Well, that's disgusting. My cheap junk HP computer just wiped out my reply to you. What a PITA. I'll try to reconstruct. My reply to your grapeshot loaded cannon would be my P.O. Ackley .270 built on a Mauser model 98 action. To hell with a fair face to face fight, I'll take you under fire from 5-600 yards away.
At any rate do you have cannon competitions in your country? I presume it to be Britain but don't know if that's so. Lots of reenactment clubs and societies here in the states along with competitions with cannons, mortars, etc. It would seem that mortars were actually the most accurate. I recall that the Royal Navy had some large ship mounted mortars during the Napoleonic wars but that comes from reading the "Hornblower" novels so that's not from diligent historical research.
As an aside, most people know what "shrapnel" is but few know that it's named for Lieutenant-General Henry Shrapnel (1761โ1842) who invented the bursting artillery shell. I find the history of firearms from the most primitive hand cannons to the most modern rifles to be fascinating. It has all culminated in the fixed cartridge weapons that achieved their most interesting developments between the 1860s through the early 20th century. Everything else has been refinements of existing technology. Guns of the late 19th and early 20th centuries are the most interesting to me. That's when real innovation occurred.

All fair in love and war. Your .270 is accurate. Assuming you are using a single 90 grain projectile that is accurate, you haved to contend with 75 150 gr projectiles travelling at about 1020 fps up to 900 yards. At your location 600 yards away there will be a spread of about 100 square feet, which means that you being about 6ft x 3ft or 18 sq ft will get 0.18 the number of projectiles or 14 of them. Not sure you would win to be frank T. You would have 2 in the head, 1 in each arm and 2 in each leg leaving 6 for your torso. I am not in the UK and we do have cannon competitions held by a pytotechnic and gunpowder manufacturer. These go with the high powered rockets.

I doubt your ballistics for your 2 pounder but have nothing to disprove it. Effective range for a shotgun is usually considered to be around 30 yards and that's with a choked gun. Your 75 projectiles would be traveling at 1020 fps at the muzzle. No choke so cylinder bore spread. However, you have the cannon so it would make an interesting experiment. Let's see a target from 600 yards using .5 inch balls. The old girl looks like she could use a little exercise so show us what she can do.
Just curious but what country do you call home?

Those 150 grain balls will travel a good distance with the right trajectory. An alternative is the following. How many of these 0.5 cal balls will fit into a 6cm shell one layer the inner core being black powder explosive. These lead balls are exactly 1cm in diameter, the area of the ball if cut in half being 0.79 cm 2 The shell wall is 0.5cm thick which means the centre of the balls occupy the space 1cm from the outer surface. They are packed up on FFFF black powder for bursting charge, obviously 14 cm 3. (100gr = 6.48cm 3, so that of be 216 grain black powder bursting charge. The surface area of the sphere these balls have to occupy will be 4pi.r 2 or 78.5 cm 2. This means that I can fit 99 of these balls just above the bursting charge minus one ball for the fuse. The trick is getting this thing to explode while 15 metres above your head; only some of the balls are going to head downwards. Might pay to wear a good tin hat.
