The last time I visited Wilkes, about 10 years ago, they had a very nice little Lang that has been converted to 9.3. I was told that they were doing a lot of this as noone could get brass etc to load for the 400/360 anymore. It wouldn't shoot well though and they refused to sell it to me until they worked it out.

I got a letter about 6 months later telling me it was ready and to respond by a certain date if I still wanted it. The date was already past and when I called they said they had sold it.
