That's hard to answer, as
this barrel does not transit from the radius to the taper...The sight base thingie is straight (in profile)...but to mill the radius on this one, I used the rotary indexing head...180º is rounded; the two sides are straight...and I used a 1/4" 4-flute ball end mill to mill it...
...But on a 4" or 6" barrel, I have a tool bit ground to a semi-circle, and turn the radius...
As for going from the radius to the taper...I just eyeball it...
