single-point on a lathe with the bore runout dialed in to zero. That is the best way.

Just why do you feel the need to mess with the crown?

If your crown is cut at a right angle to the bore there's no need to indicate anything really.
So long as you can capture the OD of the barrel securely (meaning a barrel with no taper) you can just wizz the face. A right angle is a right angle regardless of bore center.
BUT if your going to go through the trouble why not set it up with a 4 jaw/spider and single point a true 11*? You may find it looks nicer and may even shoot a smidge better.
Good luck.

The gun was in storage 40+ years and had a little surface rust, owner had her blued and the smith blued face, I took 400 wet dry and buffed the face white , a q tip seems to catch a small bur that my 57 yr old eyes cannot detect. This gun does not shoot quiet as well as a '55 model I have or is a little more picky vis ammo seems to like the 180 gr best, bore is beautiful , rifling is strong. Im out of 06 match ammo and was testing with fed, win and hornady deer loads I had on hand. I usually sight in with cheap and use match to see what a gun will do. Im out of the 06, 168 and 175 gr fed match fodder.

I find the best way to freshen things is with febreeze or scented lysol spray....
Just kidding, girly moment!
Does the current crown look/measure nice and square? You might consider a slight chamfer to the lip of the bore. Just to clean up any small issues with the tip of the lands. Just a thought. Good luck either way.

bingo, You hit nail on head, ( slight chamfer to lip) . The true collector value to this gun was lost when original owner had it blued even though smith did a very nice job, Im more of a hunter, shooter pre 64 lover. I will not own a gun and not shoot it and it must shoot well to stay.
