Norseman,
Very sorry to be so late in responding to your post.
I really like my TVM. There are a few quirks, but they aren't really functional flaws.
Fit is fine - very tight wood-to-metal fit.
A few things that are drawbacks: Since it's D-weight the breach end of the barrel sits quite high in the stock. This puts the torch-hole liner low on the flat. It also makes for a tight squeeze between the lock bolts and the ramrod. Because of this the ramrod has to be tapered to fit underneath the lockbolt. That taper (read "sharpened point") is a bit uncomfortable when you need to really palm the rod to seat the ball. I suspect that because TVM is not really familiar with D-weight swamped and Roundfaced locks, they goofed a bit when placing the lock bolts? I think the lock comes without bolt holes. Thus, if TVM put the holes in for the bolts, they made it too close to the mainspring. Some of the mainspring had to be filed to make clearance for the bolt. Again, I'm not sure this is TVM's fault or what.
Anyway, I just spent a paragraph raking on my gun. I do that to be honest. Other than the pointy ramrod, these flaws have not affected the function of the gun at all. What I really like about this gun is it is just so damn easy to please. It just seems to group well with anything from 50 to 100 grains. I prime with 2F. Type of lube doesn't seem to matter, except that grease lubes require 'tween swabbing every few shots.
