My 1931 hammer 16 doesn't have chrome-plated bores; the other two VBs I have shot do. They are great until you decide to add tubes or re-choke. Then you need a savvy gunsmith who is familiar with Italian doubles and has the tools to cut the chrome plating. I have been told that the hard chrome can eat ordinary reamers, with some ugly side effects on the area of the barrel being cut.
Any truth to this, or is it just another myth?
Since my two came with chokes that I like, I haven't tried to modify them.
