About 10 or 12 years ago I was at the annual Sand and Sage gunshow in Garden City, Ks and a seller had a #1 chambered in 416 Rigby. I looked it over real good and the guy begged me to make him an offer but I don't hunt dangerous game and couldn't think of any good reason to buy it, but it sure did peek my interest. If I remember correctly it had an after market barrel installed, as I don't think Ruger ever offered this chambering.....did they?
