Just today, I cruised through a gun shop and saw a row of #3's on consignment. There was 1 each .375, 22 Hornet, 45-70, and .223. The selling prices were a minimum $1200. I owned all the factory chamberings a few years ago. The scarcest for me to find was the 44 Mag followed by the .375 Win. I can't answer your question at this time. When I get home, I will get the info you need. Someone else may find it before mw.
