Simply ingenius.
I thought the Tantal had a short barrel life? maybe read it from a bad source. If it is longer that would be a nice surprise. My Tantal shots fine doesnt keyhole even when hot, I think its hit or miss with the keyhole factor, or they fixed the problem completely on newer ones. I still an wary and wont buy another century because of the issue and am going SLR with the next 74. Either way I do like my tantal alot and would like another ecspecially with a chromelined barrel.
