I would have just picked up an ROA in the first place and would have three of them by now 
Went out to the desert this morning, just got back from shooting the Pietta 1858, Colt Walker and the new to me ROA.
Started with the 1858, kind of, the cylinder latch is messed up.
Did shoot 2 cylinders out of it, but the latch at half cock is coming up and locking the cylinder and have to disassemble it and put it back together.
It is now locked up sitting on my bench here at the house.
Will tear it apart and see what is wrong with it.
Hopefully one of the parts from the spare parts kit I got from Cabelas will fix it
Next was the Walker.
Shot 2 cylinders wth 40gr of Pyro p
Shot 2 cylinders of 50gr
Shot 1 cylinder of 60gr
No problems.
Oh, the .457" balls now shave off a full ring instead of a half moon as with the .454"s
Now comes the ROA.
This thing is sweet
I kind of lost count of how many cylinders I shot this morning out of it.
Powder charges were 30-35-40-50gr
Very accurate, never bound up(guessing 8-10 cylinders full)
The Treso nipples came yesterday and the #11 CCI's worked perfectly.
No jambing from the blown nipples(they just rotate around and fall off).
So now I am thinking of returning those 2 extra Pietta 1858 cylinders that I got that do not fit in my gun, instead of getting another 1858 and put the money toward another ROA.
Have not decided yet.
Well, it was fun today.
