My way of doing things like this is what Kutter said. I like a little at a time. If it grows on me, then I go further. Besides, I don't always know what I will really be happy with at the time. I have a 30" Fox in Texas having an extra set of 32" barrels fitted to it. They are in the white..........finished except for a bead and bluing. My instructions were to fit the barrels, send the gun home to me, I will shoot it 6 months too see if I really like the 32" barrels as they are, or if they need some further striking, then I'll send it back. As I said, I just like a little at the time. That is not to say that I have never considered doing a full blown custom Fox "all at once", I've just never gone through with it for the afore mentioned reason.
Have fun with it, Tom..........SRH
