The other one has a 1/16" concave radius for the thinner walls of tapered barrels.

These lathe tools finish cut the crown and rib in one operation.

I use a 45 degree crowning cutter with a bore pilot to actual finish the cut on the rifling.

Figured there was a better way to skin the cat. I finally picked up a muzzle tool with a pilot a while back, but have not done a barrel since I gat it. My way works, But, a lot of fiddling to get it looking right. One interesting thing is, I studied a lot of S&W muzzles when I first started to cut one down. Their is a lot of variation from one to the other. So, "just like factory" has some leeway.
