"Shooting the .58 Cal Remington Transformed Rifle"
Mighty cool, 492 grain Minies at supersonic.
But the .50-70 Gov't. came before that upstart of 1867.
I was bluffed on that last hand !

Cases for it are made from 24 ga. Magtech brass, sold here: https://www.ammunitionartifacts.com/unitedstatescartridgecases/58-caliber-roberts-conversion

"Only 5,000 Of These Rifles Were Manufactured By Providence Tool Company In 1869-1870 For The Roberts Breechloading Arms Co. Of New York City. The Design Was Patented By Brigadier General B.S. Roberts In 1867. They Were Originally Manufactured For The New York National Guard But Were Ultimately Sold To The State Of South Carolina After The Legislature In New York Failed To Appropriate The Necessary Funds. They Were Reportedly Used Until Around 1890.
Remington Arms Company also chambered their Rolling Block #1 Action In This Caliber Using Surplus Civil War Barrels."
