Ruger has done the .358 Win in several versions. The original M77 "R" 22" flat bolt and standard, the M77 RS 18.5" and 20" carbines, the Mark II Standard "R" 22" and a 25 piece run of Mark II International (RSI) 18.5" (1993), the Mark II Frontier 16.5" Target Grey and Blued, the Hawkeye Standard "R" 22" All-Weather and Blued (ugly matte), the Hawkeye Basketweave Standard American Walnut & Circassion walnut versions, and now the American runs. I have owned all of these except the American version... and I am probably forgetting one or two.
