500 Nitro,

I have a copy of Barn's book at "home" but ye gads I am at the office. I have a forty-five minute drive one way. Nevertheless, I have tentatively bought this gun sight unseen - more or less. I could find not information on it via google. I will give it a gander in Cartidges of the World this evening. My curosity was getting the best of me.

Best
