In 2008, Sturm, Ruger & Co. introduced two new M77 Hawkeye “extreme hunting rifles” using cartridges developed by Hornady. These rifles were offered in .300 RCM and .338 RCM.
While the guns are no longer built or sold by Ruger, they are an interesting part of the company’s history. If you have one of these great rifles or are looking at buying one from a friend, this article might be of interest.
