I inherited a prohib a few years ago and the CFO sent me a letter demanding that I explain why it should be preserved. I had heard about this sort of bs before, but it was the first time it happened to me. I already owned many restricteds and prohibs. The fact that I said it was for a collection may have been relevant. It may be different of you say you want it for target shooting. It may also have been relevant that this was the first prohib I acquired. All my others became prohibited after I bought them.
In the same envelope as the letter, the CFO sent me the transfer papers for someone else's gun. I forwarded them to Gary Breitkreuz, and I don't know what he did with them.
