Hello, Erikamills18:
I suggest you contact Buffalo Arms in Ponderay, ID at 208-263-6953.
They will know what is currently compatable. Over many years, I have found company literature indicating a particular hand priming tool was suitable, especially "universal" ones, to be incorrect.
There have been some semi-custom re-de capping hand tools, but they are out of production. I use one from Meecham Tool, who is out of business. It takes CH4D shellholer #57, which is for the 50 Sharps and 50 Spencer cases. There will be some wiggle room in all of them to accommodate minor variations in rim OD and thickness. Please let us know what you learn. Thanks. Smiles.
