Obsolete Ammunition

[Goatboy708]

I have an old rifle my grandfather gave me. It is a rolling block rifle that is similar to the old Remington Civil War rifles. Its called the Modelo Argentina and is made by Remington. This rifle is in great condition and I want to soot it, but it has an obsolete round. It shoots .43 Spanish, which from what I have read is .439 and 385 grain bullet and uses black powder. I was wondering if anyone knows a good company that produces these cartridges. I found some in a Cabella’s catalog years ago, but they were $80 for a box of twenty. I have not seen them since. I have found reloading equipment but I am not that experienced reloading. All the reloading I do is a few 12 gauge rounds every now and then. Thank you for your time.
