I don't think any precarve stock is going to be perfect. There are just too many variables involved, especially if they are sending a stock like in my case where I simply ordered the barrel channel size to my barrel but didn't actually send them my barrel(they didn't ask me to send it either). Surely then there will have to be inletting done do get it to fit.
Back when I bought my two other guns from the old TVM, both precarve stocks had some issues. The first one, my Lancaster, I had to send the first stock back when I discovered the lock area included about a 6 inch long crack in the stock that ran from the wrist through where the locjk mortise was up into the forearm. The second stock then sent me was ok. My smooth bore's stock has several knots in it where the cheek rests. Not a structural issue, and it did turn out looking kinda cool after I finished it, but had I not had issues with the people I dealt with, I would have sent the thing back. What I'm saying is, you are liable to get a lemon from anybody. Regarding Pecatonica, I've had good experiences so far, and alot of people I know and have talked to say they are a first rate outfit.
