[Dogbone38Super]

Any recommendation to recrown a .257 Roberts barrel. Preferably in Seattle Tacoma area. Brownells tooling is all out of stock.

Depending on the defect, if only minor, valve grinding compound and a 1/4" brass round head bolt chucked up in a variable speed drill will clean up many lightly abused exit wounds. Pack the barrel end full of hard pressed in & then oiled toilet paper to keep the grit from migrating further in.
Even if you need and find the reamer, still good to polish it up afterwards and I like to throw on a little cold blue. If you go for a professional, do not accept any mill marks regardless how they down play it. It just aint right.
I'm still using an old Clover two sided valve compound can I bought new. it has medium and fine grit albeit after sixty years it is getting pretty dry now and has to be wetted up some before each use...

Thank you, I have seen that done many years ago. Might do the trick here.

I ordered crowning cutter tools from Manson Reamer. This crown looks like it was dropped hard on concrete.
