Mine is not near a pretty as Godogs57's.
This is a 1891 produced Model 1886 re-barreled at some point to a 33 WCF. I do not know what caliber it originally was. I have not ordered a letter yet. I can tell it was originally a round barrel case hardened receiver rifle and the mag tube on the rifle was shortened from a full length one. I bought the rifle out of Montana.
I am running Jamison brass, 200 grain FN from Buffalo Arms and 39.0 Gr. IMR 4895.
John Barsness article in the Dec. 2016 Rifle magazine (I think tha'ts the issue) was very helpful as was his advise given on here.
