Yes,
I had one of my Vetterli's converted to centerfire through them.
Bernold struck me as old world, which is to say he's a bit gruff when first talking with him and gave the impression of not suffering a lot of foolish questions as he's so busy. Just be neutral and to the point, I decided. He expects you to order something rather than call up to chitchat.
The Vetterli was my obsolete cartridge reloading project that I worked up rounds for myself, so I have not ordered ammunition from them. Everything else I reload the components are commonly available.
I would say that if you have an obsolete calibre you want to bring out of the gun safe and shoot, they are the best game in town besides doing it yourself.
It took a tad longer than I would have liked to get my order(six months or thereabouts), but oh well, I am a fairly patient man I guess.
