Not yet.
I have an order of Kerr bullets, and the mold for Johnson & Dow. I plan to cast those this coming weekend. I also have the Eras Gone Dragoon bullet and an Old West mold called "44 Walker" which might be a slightly modified version of the original 217gr Picket conical originally called out in the Walker contract.
I hope to weigh and measure them this weekend. I probably can't shoot them until March though.
Here, I just have a Pietta buntline and Pedersoli copy of the Remington New Model Army.
In Texas, I can try them in a Colt Walker Gen 2, Colt 1860 Army Gen 2, Colt Dragoon Gen 2, and a Ruger Old Army. I have chronographs in Texas, so I can also get some useful data, like how much powder will fit with the various conicals and round balls with associated velocities. Anyway, that is my plan.
