Hey guys, I just received a Charles Boswell box lock I had brought in. Gun was made in 1905.
I am going over the gun and everything is as advertised. The peculiar thing is the gun won’t close all the way with a Winchester AA HS hull. No problem with an RST (Cheddite) hull. Upon closer examination, the O.D. of the Winchester brass rim is .002” larger than the RST. The rim diameter is just large enough that it won’t fit into the rim cut in the chambers of the barrels to allow the gun to close. I filed down the rim on the Winchester .002” and then it fits properly to allow the gun to close. Does anyone know if it is an easy fix for a gunsmith to open up the I.D. of the chamber rim cut .002”, as to allow the use of Winchester hulls? Has anyone else run into this?
