Well after hunting all over the LGS and the internet, I found the Uberti 1873 I was looking for. I found a place called Kones Korner in SD. I call and the gentile man said he had one, NIB. I said he was the only in the USA that had one, and he said that he was the largest Uberti distributor in the country and according to his computer, he has 70 of them in stock.*
I ordered one and now I am waiting for it to arrive. I ordered it last Thursday so I should be getting late today or tomorrow, I hope. I ended up paying $1084.00, that includes the shipping and the FFL fee on my end.
So when I get, I will probably be trying to pick the brains of those that have one of these 357 mag lever rifles for loads and bullet styles for this rifle.
* This is what the voice on the other end of the phone was telling me, I have no Idea if it is true or not.
