I spent all day yesterday and a couple of hours this morning, scraping and stoning all of the burned flux and excess solder from the barrels. Then I took them to my tool and die maker friend's house where we set them up in the Bridgeport mill and machined the front sight ramp and the quarter rib down to their final height. Below are 4 photos of where things stand now.

Below is a shot of the barrels fitted onto the action. Tomorrow I'll take the gun to the range and put a half a dozen proof loads through it. Then it's time to cut the mortises and dovetails for the scope bases, front and rear sights, and the grooves in the front ramp to hold the hood. Still a ton of polishing to do but that will wait until after the regulation is complete.
