I think they lost because the trials were to find a way to convert the Springfield Mod 1863/65 to fire cartridges and the Springfield employee Allin's conversion used the existing lock, stock, and barrel (modified to fit the breechblock). It was therefore cheaper. I thought the Springfield mod. 1871 was a version of the Remington rolling block.
