I just took a look at your suggested .pdf and loved it, many thanks for providing it! I goofed, and interpreted Figure of Merit numbers as whole group sizes. To keep the original powder load and bullet weight he reduced the bore caliber to .45, and designed a 1:20” twist hexagonal – polygon – rifling to achieve maximum performance. Paper patched bullets were used or cartridges. He played with the rifling twist of the .577 rifle muskets and realized that bullets longer than 2-3 caliber length have a better stability if the rifling twist is faster. It is 530 grains in weight and is wrapped with paper. Best regards, 5700 Whitworth rifles manufactured by different British companies. The hexagonal rifling needs a mechanically–fitting bullet and that is exactly what Whitworth designed. https://en.wikipedia.org/wiki/QF_4.7-inch_Gun_Mk_I%E2%80%93IV#United_States_service. The side mounted scope allowed the use of the standard iron sights in times of need, when long range accuracy was less important when compared to the possibility of fast aiming. No one knows. It had a Figure of Merit of 11.62 feet. Roughly 30% of a recoilless gun’s powder charge launches the projectile, the other 70% provides the “counterweight” that keeps the gun from moving. The making of the bullets intrigued me. Simple, fast, and not likely to mess things up. https://en.wikipedia.org/wiki/Polygonal_rifling If you did not clean, things got fairly tight by about the third round. 1 x 2.75" (70mm) gun tube (also 2.17" gun tube featured). See http://sharpshooters.cfspress.com/arms.html. Image from the Public Domain. Even if making black-powder recoilless was technically possible, I doubt if they would found it useful in 1860s. We do not sell any of the items showcased on this site. Bullet molds should have come with the full rifle package, right? Hardened mechanically fitting bullets could be used, or soft lead cylindrical. Does it mean that flanks of bullet were in helical form, as speculated before? See ‘Measuring Accuracy’ which explains Figure of Merit and includes the original report from the Times newspaper with the Enfield / Whitowrth results. ‘Why, they couldn’t hit an elephant at this dis….’ Interestingly, Whitworth also made and sold cannon operating under the same principle, both muzzle and breechloading. Army preferred to use standard paper–wrapped cylindrical bullets. I’ve seen that quote as: He used 1:25” spiral for the .577 bores, but also noticed that the increased weight of the bullet needed an increased charge as well to have a flat trajectory. You are right about the Panzerfaust, and it does prove that at least a very low velocity recoilless gun using black powder was possible. This statement is based on an advertisement that appeared in the New York Tribune on March 12, 1862, offering 50 Whitworth rifles for sale with 15000 cartridges. That meant that it could be used with fouling that would stop a Whiteworth. 10/16/2017 Army armed with similar small bore rifles like the Kerr. There’s another reason besides cost that the Whitworth rifle did not become standard issue: It got its increased performance partly by close tolerances bullet to barrel, and so was less tolerant of powder residue building up in the barrel. The cylindrical bullets were upset to fit the barrel when fired, like a very long Minie ball, so they had to be made from soft lead.
