Do you shoot conical or ball in them? I preferred ball in mine but they did have conical. Some liked them but ball was the most popular. Remington replicas were the most popular for those that liked to shoot targets as they were similar to your solid frame revolvers. Colts were often taken apart and cleaned until the wedge system got loose. This also caused issues as they were not supported at the top of the cylinder. They had a very large cylinder pin with grooves that were designed to keep things functioning when getting fouled. The Remington had a pin release so that the cylinder could be removed. The Remington's were fine pistols and I had a couple. They all needed a taller front sight for target work. Instead of installing modern target sights I preferred to just raise the front blade. Don't have pictures of either but the Remington 1858 was more in line with your British designs.
I have seen pictures of the big Tranter, a 577, that must have been a handful. Gathered it was designed to use against spear and sword toting enemies. The British has issues with the 303 in India and the US in the Philippines with people that did not like them there. You solved the issue at the Dum Dum arsenal, the US filed the bullet noses on the 30-40 Krags. We went to the 30-06 you changed the loadings for the 303 from the 215 to the 174 grain bullets. The US had problems with the 38 long Colt with officers getting split by a Kriss. They were said to have unboxed the old 45 Colt single actions for them. Whether they worked better no one said but as the Colt was a better pointing revolver and easier to shoot it might have worked better with more solid hits. Led to the development of our 1911 45 semiauto. From what I have seen the British liked the 45 caliber in revolvers also for military use. Seen lots of old Webley's pictured.
