Bwana,
Thanks for offering to find the article. I should have kept it in a safe place. In fact it may be in a safe place so safe I can't loose it.
I had mine made by Jim Tarte? Who was the gunsmith at Gander Mountain before they went big time just one store in Wilmot WI.
I think Jim made the first ones up I have no idea how many were made but I think a few others were made. I bought a barreled action in .458 and he re-chambered it as he had the reamer. Boots Obermeyer may have made the reamer but I am not sure.
The brass was made by Jim Bell while he was in Bensenville, IL I remember him telling me to get what I wanted with the head stamp as he had just a small amount left.
Cheers,
Laurie
