Which ammo for which model Rolling Block?

There were many 43 Spanish loadings. The most popular was the 11.15x58Rmm for the 1879 Argentine model but there were many others. The original version was the 11.5x57Rmm Reformato. The 11.43x50Rmm, 43 Egyptian. The 11.4x50Rmm Brazilian Comblain M74. The 11.7x51 Danish.

These were all called 43 caliber cartridges.

43 Spanish was at one time more plentiful and cheaper in the US than 45-70 was at the same time. That is no longer the case.

43 Spanish Reformado chambering

there are two versions of the Reformado, one is the true .43 Spanish Reformado, with original cartridges and a .451" diameter brass jacketed bullet. The other Reformado is a true .43 Spanish that has been rechambered with the barrel left the same size as the original .43 Spanish (11.15 x 58R) which uses a .439" diameter lead bullet.

Remington rolling blocks in .43 Spanish can have bore (groove) diameters that vary from .439 all the way up to .445 and occasional .450. Apparently Remington workers were not too careful about which barrels they were screwing into receivers on large contracts to South American countries. Remington was also selling their version of .44-77 which was very similar cartridge case but .445 bullet. Slug the bore if you intend on shooting the gun. I
