Synthetic stock didn't fit, may grind out the old bedding material and re-bed. Put it in Ol' Ugly's original birch stock for now. It was my first stock refinishing project and it looks pretty good, if I do say so myself. A bit of forend pressure but other than that a perfect fit. Bore is so badly fouled I just checked to make sure I had an extra can of Wipe-Out on the shelf.
Seems this old gun has been carried a bit over the last 40 years, fired little but hasn't been properly cleaned in at least 100 rounds, maybe longer. Not sure Even Uglier is going to make it to the range today.
