Sorry about the pictures as they aren't the best. The striations are quite consistent from each other meaning the spacing is very consistent. I had a gunsmith look at it today and he stated it looked as if it had not been shot much at all and that he has seen some T/C barrels look like this.

So my two options are to shoot as is or rebore it. Talking to Bob Hoyt today he will charge $125 to rebore it to .54 and 1/60 twist. Open to opinions.
