rounding end of muzzle

[AMMASHOOTA]

how do you round the end of the muzzle on a lathe -- similar to stock remington barrels?

 

[John Kielly]

The couple I've seen done that way grind a tool to the radius they want.

Or you can buy it already ground from Pacific Tool.

I ground a couple of tools. One for quite small barrels and one for slightly larger barrels. If the diameter is large enough I cut a flat recessed crown. Many hunting rifles do not have a concentric bore/barrel diameter relationship... when you cut off some barrel and crown you find this out. After the 'round' radius is cut as best possible I finish the crown with a very light chamfer cut with a 60 degree piloted reamer.
