Ball burnishing?

[Mk VII]

I've got a Fultons one and the crown is flat on that as well.

Spotted Peter's response earlier and went looking for info on ball burnishing. Only found references to surfaces in general, but applied to a rifle barrel it would be exactly as he has described.
I'll see if I can find where I got my info from, I may have a crossed wire- the method may be for another type of finishing process.

Was there a defined list of work that went into a "Regulated by Fultons" rifle? Or was it the choice of the customer what was done to his rifle?



Note, just found the process I refered to earlier is "draw lapping", not ball burnishing.... apologies

Another to add and confirm. I have a REGULATED BY FULTON marked barrel that also has flat faced muzzle with tiny, tiny chamfer into the bore.
