Mr. Calhoon was making the 19's for quite some time. The 20's took off and became factory, but apparently he has sold enough of them and has had enough of a following to keep on keeping on.
He lives about a mile down the road here and I have asked him before if he'll do standard rebarrels, truing, etc. His reply was that he is so busy with conversions and making bullets that it's all he does.
