whitworth rifle ammo

The most common type of Confederate Whitworth rifle was a 33” barrel rifle, featuring an Enfield pattern stock with two iron barrel bands, iron sights and Enfield pattern lock. At CW battle sites many more cylindricals have been found. According to the Wikipedia article, the Whitworth rifle had both hexagonal and cylindrical bullets, both with paper cartridges. With a reloadable gun it would probably be a much bigger problem considering the large amount of powder neede, especially if the barrel was rifled. http://sharpshooters.cfspress.com/articles.html#sir_joseph_whitworth. By all accounts they don’t work the best, such bullets are best made in a factory by swaging lead wire. Armstrong-Whitworth went on to become a major aircraft company. From reading the below it seems that was not an issue. Which were much less dangerous to their own troops overall. Fouling could be a problem, How many rifles reached the CS troops? It could literally be dropped down the barrel! I’ve seen that quote as: Whitworth Rifle production took place overseas in Britain which made its availability in the States rather restricted. Talking expensive gun . Strangely enough the Armstrong and the Whitworth engineering company’s merged in 1897, 10 years after Joseph Whitworth had died, and well after both had abandoned hexagonal guns. The barrel was made of high quality cast steel and it was compressed in a fluid state. The bullet was quite tight and twisted as it came out. We know about cca. Sir Joseph Whitworth is quite the famous name in engineering circles, credited with the development of such things as Whitworth threading (the first standardized thread pattern) and engineer’s blue. Whitworth made a 12-pounder breechloading field gun on the hexagonal bore principle; http://civilwarwiki.net/wiki/12_pdr._Whitworth_Breechloading_Rifle. Interestingly, Whitworth also made and sold cannon operating under the same principle, both muzzle and breechloading. There’s well over 600 recorded in the now. It is without question that the most feared rifle of the American Civil War was the British– made Whitworth rifle imported by the Confederacy and delivered by fearless blockade runners thru the blockade of the U.S. Navy. No knowing if a Whitworth was involved. Probably not. (Showcased structural values pertain to the, (Showcased powerplant information pertains to the, (Showcased performance values pertain to the. It might have been Armstrong , nor Whitworth. When used with imported bolts and shells, they seemed to work pretty well, but with ammunition produced in the South as the blockade was tightened, there were problems. The center of the group (or Mean Point of Impact) is plotted and then the distance between the MPI and each shot is measured, added up and averaged. The figures Ian uses are derived from the same British report that I included in my article. Was any comment made on the influence of using a “grease cake”, over the test period, on accuracy (My apologies Ben, I have not yet read all of the link you sent but I will, as it is fascinating – thanks again). Yes, but Whitworth ammunition usually came as pre-prepared rounds just like most rifle ammunition of the era.

Simple, fast, and not likely to mess things up. You poured the lead in the to of the mold, and used a special mold handle with a rod to push the bullet out of the mold. Maybe a few tens, maybe a few hundreds. Roughly 30% of a recoilless gun’s powder charge launches the projectile, the other 70% provides the “counterweight” that keeps the gun from moving. See ‘Measuring Accuracy’ which explains Figure of Merit and includes the original report from the Times newspaper with the Enfield / Whitowrth results. The cylindrical bullets had a small hollow base which would expand and grip the hexagonal sides of the barrel, which required that the bullets be made out of very soft lead. For those not familiar with Whitworth tread, it has profile peak angle 55 degrees instead of US national standard or metric thread 60 degrees. Guess who got nailed? There were also reliability problems with the breechloading versions – the screw type closure tended to jam tight and not want to open – and this was a big enough issue that the breechloaders were often used as muzzleloaders by simply leaving the breech mechanism shut. WW rifling worked with muzzle or breech loaders. It certainly shot better than I did, and I am told that the originals (if in good condition) were even better. The WW shot almost as well with a soft lead cylindrical bullet. One thing that is clear from the Tennenet book, and what’s been said on this discussion, is that a large part of the issue/complaint about fouling in the Whiteworth was simple down to the fact the bullets actually fitted the barrel! And incidentally causes the horrendous blast of flame and gas behind it that creates such a large danger space for the gun crew, and advertises the gun’s position to everybody within a thousand-yard radius. They were not available in large numbers, but they were excellent rifles and put to use as much as possible. Read Tennant’s “The Story of the Guns” page 58 for the details. Even if making black-powder recoilless was technically possible, I doubt if they would found it useful in 1860s. 1 x 2.75" (70mm) gun tube (also 2.17" gun tube featured). Bullet molds should have come with the full rifle package, right? I doubt one could make a well-functioning recoilless gun with black powder. If I remember correctly, original Whitworths used gain twist rifling. I know recoilles guns use much more propellant than conventional guns. A rocket would be a different matter, but they tend to be very inaccurate and can be dangerous for the crews. the powder charge and bullet were contained in the “paper” cartridge, actually thin cardboard about like a modern business card. High powder demand is also the reason why the Germans did no use medium or heavy recoilless anti-tank guns guns in WW2, despite having some well developed designs by mid-war. Will it come with dedicated bullet mold? Whitworth made a total of about 13,700, selling them to high level competitive marksmen and wealthy shooting enthusiasts. How it would affect accuracy? (there was a whitworth rifled target rifle in the main homestead office, a rifle by Eli Whitney, there is a long story there) Unfortunately I have none of those bullets now, but they had quite a deep hollow base with quite heavy skirting. German Cold War-era Armbrust AT weapon is example how to solve entirely problem of flash (thus CAN be used inside building, unlike most AT recoilless rifles). It arrived a day late, and the designer thought of many improvements after reviewing the first few hours of battle, but it neutralized the CSS Virginia (formerly the USS Merrimack) and saved the wooden ships that had survived the Virginia’s first foray. And this was long before EDM machining. At least at this anecdotal level. The standard load of the rifle was between 70-85 grains fine British powder that propelled the 530 grain bullet. But if the bullet expanded properly, it left the gun, as it were, ‘sponged out’ after every shot. The original bullet for a Whitworth was indeed hexagonal with an inclined hexagonal form to fit the rifling twist, and reproduction bullet molds are still made today by Peter Dyson in England. I used to own a ‘D’ series Whitworth very similar to this rifle but without the scope….and would pass on some observations. The shot group measurement in use at the time was the Figure of Merit or what we now call the Mean Radius. I just took a look at your suggested .pdf and loved it, many thanks for providing it! Rather it would perhaps be like ramming a pre-Minie ball (or bullet) to a muzzle loading rifle, which was so slow that it could not replace smoothbore muskets in general infantry use. The residue could accumulate in the corner of the rifling causing the bullet to be hard to ram down. You are right about the Panzerfaust, and it does prove that at least a very low velocity recoilless gun using black powder was possible. The high-speed gas flow out the back has to balance the mass of the projectile going out the muzzle to achieve the recoilless effect (M x V= momentum). One of the major drawbacks in the Whitworth Rifle's design was the breech system's fragility over the course of extended combat exposure. Please note this correction: However, the rifles were equally expensive, and were not given further consideration for military use. 5700 Whitworth rifles manufactured by different British companies. Do any bullet molds exist? Why was it necessary sometimes to deploy entire artillery batteries to silence one single Whitworth sharpshooter? I’ve bought that rifle. the flats did not actually touch each other, with the spaces in between being still rounded). Whitworth Rifle - Base Series Designation.

No surprise, they could win by numbers without the risk of adopting an immature “super weapon” technology – with the notable exception of the Monitor ironclad, where an entirely unique design was built as fast as possible and rushed into combat untested. could afford a WW. http://brettschulte.net/ACWBlog/archives/wwbullet.jpg. The original Whitworth bullets were not cast but pressed. If the lubrication were correct, ‘there could be no such fouling, even when the rifle was used constantly for a month. Having opposite sides paralleled makes things easier to draw and check. By this I mean target rifles and not issue rifles like Springfields, Sharps, and Spencers. It is 530 grains in weight and is wrapped with paper. Does it mean that flanks of bullet were in helical form, as speculated before? The cylindrical bullet, however, easily upsets into the hexagonal bore under the influence of the explosion of the charge of between 80 and 90 grains of fine rifle powder used for this particular firearm – recovered bullets fired from a Whitworth rifle are as hexagonal as their factory-made counterparts. | Content ©www.MilitaryFactory.com.
