Navy Arms/Uberti Schofield

["Big Boston"]

I've owned this, my only Schofield, for about a year now. I have a few other 45 Colts, and I had issues that I traced to the throats on the cylinders on some. To remedy I bought a reamer and gave them all a "tune up". I left the Schofield to the last, I wanted to hone my skills before doing this one. I set up the tool and unlike the throats  on my other guns, the reamer pilot dropped right through. I steadied the back of the reamer in the chamber and reamed the last quarter inch of the throat. 

 

 

All the throats were the same, which I found rather odd. But even odder was that the chamber was a bit of an oddity as well. There is no defined end to the chamber. The chamber is normal for the length of the brass, then it gently tapers to the end. It has me puzzled and I'm wondering if I just changed a designed in feature. I've not test fired it yet, but I can't see it being any worse for leading the forcing cone and first part of the rifling than it did before I reamed the last bit. 

 

Was the blended/tapered chamber a thing? Or is it just Uberti copying a worn out Schofield Cylinder? Or was someone in there before me?

 

I'm tempted to just shoot 45 S&W in it, with the sloping funnel like throat, I cant see it building up much of a crud ring.

The build up, or lack of carbon (crud) ring in the chamber isn't related to the throat.  It's a product of combustion of the propellant.  Some propellants don't leave a carbon ring and some leave a pronounced carbon ring.
