Does the ”honeycomb” construction of a revolver cylinder make it stronger compared to a single barrel? The reason why I’m ask is because I’m trying to figure out the minimum safe wall thickness for a single shot black powder pistol. The pistol I’m making will be loaded with a patched .53 roundball (weight 231 grains) and the maximum charge I’ll ever use behind that roundball is 80 grains of pyrodex P (FFFG). In which maximum pressure range will such a load be within? It’s hard to find pressure values on black powders loads, however it seem to me that black powder is in most cases low pressure compared to smokeless. In comparison, will the load I’m using have higher or lower pressure compared to the pressure generated by a 28 gauge modern shotgun?
According to this resource https://www.cip-bobp.org/homologation/uploads/ciptexts/a-4-1-en.pdf the minimum wall thickness at the chamber area for a 28 gauge shotgun is 1.05mm of the best steel, and 1.9mm if you use the weakest steel that’s included in the list. With black powder, where does the pressure peak? In a black powder revolver, does the pressure peak in the cylinder or in the barrel?
